WAT) [9], Warsaw, in cooperation with Warsaw University of Technology
(WUT) [10], Warsaw University [11], and Wrocław University of
Technology [12] in Jastarnia on 27-30 September 2016. Symposium
is a representative portrait of the laser technology research in Poland.
Symposium Proceedings are traditionally published by SPIE [13–21].
The meeting has gathered around 150 participants who presented around
120 research and technical papers. The Symposium, organized
every 3 years, is a reliable image of laser technology and laser applications
development in Poland at university laboratories, governmental
institutes, company R&D laboratories, etc. The SLT also presents the
current technical projects under realization by the national research,
development and industrial teams. The works of the Symposium, traditionally
are divided in two large areas – sources and applications.
The main topics of SLT were: laser sources in near and medium infrared,
picosecond and femtosecond lasers, optical fiber lasers and
amplifiers, semiconductor lasers, high power and high energy lasers
and their applications, new materials and components for laser technology,
applications of laser technology in mea surements, metrology and

The laser fading process is acknowledged as a very strong alternative compared to the conventional physical and chemical processes used for aged-worn look on denim fabrics. In this study, the beams from a CO2 (10.6µm) laser was used for the fading of denim fabrics. In terms of both color and mechanical properties, it is found that 100 and 150µs pulse times are suitable for laser fading process of denim fabrics. This study aims that the effects of laser beam on denim fabrics were investigated and optimum process conditions were determined by tensile strength, tear strength, rubbing fastness of fabric. According to the observation from this project both tensile and tearing strength decreased (respectively on both warp and weft direction) and color fastness to rubbing was decreased in significant level comparison with both before and after fading effect of denim fabrics.

This study is a comparative tensile analysis of pulsed mode laser soldered rats’ skin with gelatin and chitosan as soldering materials mixed with ICG as chromophore. Sixteen females Wister rats grouped into four; Gelatin-ICG, Chitosan-ICG, Gelatin-Chitosan-ICG and Suture (control) treated groups.4 incisions each 1cm long were dorsally made and irradiated for 15 second at 1 Watt to attain fluence of 53.74 J/cm2 per spot. Two animals from each group were randomly drawn and sacrificed at fourth (4th) and seventh (7th) days respectively and the incision sites were excised for tensile strength measurement. At 4th day post-irradiation, no significant difference statistically (p<0.05) found in comparing the mean tensile strength of gelatin-ICG and gelatin-chitosan-ICG groups where gelatinchitosan-ICG has higher mean tensile value than gelatinICG whereas these two groups has higher mean tensile strength statistically significant (p>0.05) than chitosan-ICG group. 7th day after irradiation, there was statistically a significant difference (p>0.05) between the mean tensile strength of chitosan-ICG and gelatin-ICG treated group with chitosan-ICG having higher mean value than gelatin-ICG group. The mean tensile strength for gelatin-chitosan-ICG group was statistically significant(p<0.05) and much greater than both chitosan-ICG gelatin-ICG groups. However, the mean breaking time for gelatin-chitosan-ICG was significantly higher than other solders and suture control at both 4th and 7th. Thus, the gelatin-chitosan-ICG mixture as soldering material was found to have highest tensile strength and therefore most effective.

Direct Metal Deposition (DMD) builds metallic parts layer by layer directly from the CAD data. The process has been widely used in manufacturing, part repairing/coating and metallic rapid prototyping.
However, success of this technology depends upon the final quality of the components produced, which in fact strongly dependent upon various parameters such as laser power, beam diameter, scanning speed, powder mass flow rate, etc. this paper presents a review on the DMD process, its parameters and influence of the parameters on final characteristics of the components.

In this research, two computers are used to transfer data in free space optical communication system using transmitter and receiver circuits and the distance separation between these computers is 50 m. The transmitter part of the optical communication system contains a drive circuit and semiconductor laser as a light source, while a receiver part of the optical communication system contains a phototransistor and an amplified circuit. In this research, we have designed and constructed an optical system of information transfer between two computers in practice based on the theoretical design circuits A green laser with wavelength of 532 nm and measured output power 26 mW is used. The COM port (RS-232) is used to send and receive data with " advanced serial port " program version 5.5 with a bit rate of 9600Kbps. The results of the optical communication system are achieved as sent a sequence of binary digit 0/1 from one computer to another computer using the measured transmitted power of the laser at a specific distance between computers.

In terms of sense terminology, it is possible to make use of Digital Technology to expand and modify the perception of humans' environment. The approach to design Cybernetic Extensions to expand the senses of the Human Body is being analyzed throughout this article. Under the debates on the dialectical interaction between technology-body, species-environment, creation-biocreation and human-bonding, the concept of Prosthesis presented by Tomás Maldonado is proposed as the starting point for the Cybernetic Organs design. It is predicted that these Smart Prosthesis will be designed by using 3D printers, and the patient's own cells, which will be created in Fab Labs laboratories. It will go from designing objects to designing the Human Body as an object.

Hercules is a XeCl excimer laser designed and constructed about ten years ago at the Laboratories of ENEA Frascati. It can deliver up to 10 J output energy at a repetition rate of 10Hz. Since 1992, Hercules is a laser facility available to check the feasibility of processes and/or the effects occurring to materials irradiated with ultraviolet radiation at very high energy fluence or at high intensity level or over a large area. Here we present a summary of the main mechanical, electrical and optical characteristics of Hercules, together with a selected list of irradiation experiments, including the generation of soft x-rays and re-crystallization of amorphous silicon.

Due to their unique properties, laser and optical technologies hold today an important role in the protection and study of Cultural Heritage, since they are used in a wide range of demanding analytical and diagnostic applications. Considering the rapid and vast technological development of their methodologies and tools, it is necessary to make this new knowledge more reachable and comprehensible to heritage scientists. Towards this end, a web-based knowledge platform (Polygnosis) (http://politeia.iesl.forth.gr/polygnosis/) was designed by the Institute of Computer Science (ICS) of FORTH concerning the state-of-the-art light and/or laser-based techniques, which have been developed at the Institute of Electronic Structure and Lasers (IESL) of FORTH, for advanced imaging, analysis and diagnosis of Cultural Heritage objects. This educational digital tool seeks to highlight the efficiency and potentials of modern optical and laser technologies in Cultural Heritage documentation, as well as, promote the dissemination and deeper understanding of their applications to conservators, archaeologists, art historians, material and laser scientists. " Polyg-nosis " represents accumulated knowledge regarding the selection of the diagnostic tool and the suggested methodology , with simultaneous display of examples of actual experimental procedures. The model relates those examples with the relevant terminology of the Thesaurus, the information about the object under examination and the metadata resulting from those experiments. 'Polygnosis' thesaurus is a semantically structured vocabulary organized by a faceted classification, which serves the educational needs of the system. The current study concerns the definition and classification of terms for the development of the semantically linked Thesaurus, as well as, the presentation and review of the knowledge platform, with emphasis on the supportive role of the thesaurus in such an educational resource.

During development of new methods of laser using for fouling of ships control there must be a clear understanding of species composition, quantitative characteristics and succession of fouling communities formed on anthropogenic substrates. So far, the impact of high-power laser radiation on organisms of marcofouling is fully unstudied. On the steel plates, studied in Sukhoputnaya Bay (UssuriyskyBay) and Tichaya Zavod Bay (Vostok Bay), 16 mass species of fouling of vessels and hydrotechnical structures were found. Among them, there are two alien species of particular interest — barnacle Amphibalanus improvisus and colonial ascidian Didemnum vexillum, resulting to the maximum fouling. Steel plates, exposed to the sea within one month, and with weak fouling, well fully cleaned with laser capacity from 400W to 1000W. However, for plates with 4 and 5-month period of exposure to the more powerful fouling, laser treatment was more effective only at maximum power (1000W). During the experiment it was observed that on control plates not exposed to laser treatment, microperiphyton consist of 63 species and intraspecific taxa. Among the benthic diatoms Attheya ussurensis was found in September 2015 during the water desalination to 29 0/00. The quantitative characteristics of microperiphyton in Sukhoputnaya Bay and Tichaya Zavod Bay on the plates with 4 and 5-month period of exposure were at one and two orders of magnitude higher, respectively, than with a monthly term plates. The obtained experimental results can be used as the basis for the new technology development of laser cleaning of technical installations and facilities, which are operated in an aqueous environment of biofouling.

In this work, an analytical study to detect the ratio of bilirubin in human body by determining the level of it in blood using a 532nm laser light transported through some samples of bilirubin has been presented. A second harmonic generation of Nd:YAG laser with measured maximum output power 52.5 mW was used to determine the concentration of total bilirubin in blood. Initially, the cuvette was filled with a sample of standard bilirubin level and then it is filled by a sample of blood containing unknown levels of bilirubin. The absorption factor was calculated for four samples of adults' blood and five samples of babies' blood, and the scattering factor was neglected for each sample. The unknown concentration of total bilirubin was determined and the transmitted power through these samples of blood was measured. In this work, a good matching was obtained between the results of the concentrations of bilirubin in blood using laser technique and the results of the classical medical procedure of measuring the bilirubin concentrations. Therefore, the jaundice in human was detected.

A large-aperture, long-pulse XeCl excimer laser has been used to generate a soft-X-ray plasma source. Several laser optical configurations have been employed to optimise X-ray emission, including positive-branch unstable resonators and injection by seeding the gain region of the laser with a small commercial excimer laser, resulting in power densities in the range 10^12–10^14 W cm−2. The characteristics of the plasma source for each different laser configuration and for different target materials are investigated. The most suitable source conditions (spectral energy distribution, time duration, etc.) for specific applications are discussed.

This paper describes the laser performance of an X-ray preionized ten-liter volume, electron-avalanche discharge XeCl system, operated at dc charging voltages of up to 70 kV both with and without X-ray preionization. An output energy of more than 11J uniformly distributed over a (7×10) cm^2 spot size was achieved using a multichannel spark-gap as the main discharge switch. The discharge was also successfully operated in the switchless mode, yielding a 4.8 J output energy and a 0.9% efficiency. The time-resolved gain measurements provided information on the laser discharge evolution.

The main properties of acousto-optic modulators (AOM) applied in laser technology are presented and discussed in the paper. The critical review of application of AOMs in several types of diode pumped solid state lasers (DPSSL) is given. The short description of few DPSSLs developed in our group is presented in the following chapters of the paper. The parameters of a simple AO-Q-switched Nd:YVO4 laser (peak power up to 60 kW, pulse duration of 5-15 ns, repetition rate in the range 10-100 kHz, with average power above 5 W) are satisfactory for different application as follows: higher harmonic generation, pumping of 'eye-safe' OPOs etc. The achieved brightness of 1017 W/m2/srd is comparable to the strongest technological Q-switched lasers of kW class of average power. The main aim of paper is to present novel type of lasers with acousto-optic modulation namely: AO-q-switched and mode locked (AO-QML) lasers. We have designed the 3.69-m long Z-type resonator of the frequency matched to the RF frequency of AOM. As a gain medium the Nd:YVO4 crystal end pumped by 20 W laser diode was applied. The energy of envelope of QML pulse train was up to 130 muJ with sub-nanosecond mode locked pulse of maximum 30-muJ energy.

There is a common opinion that laser technology allows measuring the distance only by directly measuring the "flight" time of the laser beam pulse to the reflecting object and vice versa. This laser technique (called pulse or time-of-flight or TOF) is used mainly in cases where the distances to the desired object are sufficiently large (> 100m). Since the speed of the light emitted by the laser beam is pretty high, it is quite difficult to measure the TOF of light, and therefore the distance, with high accuracy in a single laser beam pulse. Light travels 1 meter in about 3.3 ns, so the accuracy of measuring time should be nanosecond, although the accuracy of measuring the distance will still be tens of centimeters. Specialized microchips are used to measure time intervals with such precision. However, there are other laser technologies for changing the distance, one of them is a phase one. Compared to the previous one, in this technique, the laser system operates continuously, but the laser beam light is amplitude-modulated by a signal of a certain frequency (usually these frequencies are less than 500 MHz). The laser wavelength remains unchanged (usually 500-1100 nm laser system is applied). The light reflected from the object is received by the photodetector, and its phase is compared with the phase of the reference signal from the laser system. A delay during the wave spread causes a phase shift, which is measured by the range measuring system. This operates only if the distance to the object is less than half the wavelength of the modulating signal. If the modulation frequency is 10 MHz, then the measured distance can achieve up to 15 meters, and when the distance changes from 0 to 15 meters, the phase difference will change from 0 to 360 degrees. A change in the phase shift by 1 degree, in this case, corresponds to the object displacement by approximately 4 cm. If this distance is exceeded, an ambiguity arises, to be precise, it is impossible to determine how many wave periods fit in the measured distance. The modulation frequency of the laser system is switched to solve the problem. The simplest case is the use of two frequencies; the distance to the object is determined at low frequency (but the maximum distance is still limited), the distance with the required accuracy is determined at high one-with the same accuracy of phase shift measurement, herewith, the accuracy of distance measurement will be much higher using high frequency. Since there are relatively simple ways to measure the phase shift with high accuracy, the accuracy of distance measurement in such laser system rangefinders can reach up to 0.5 mm. It is the phase laser technique that is used in range measuring systems that require high

Since 8 years there is organized twice per annum a research Symposium, which is known under the abbreviated name of the IEEE-SPIE WILGA in the national research community of the photonics, web technologies and electronics for the high energy physics experiments. The WILGA Symposium is gathering young researchers, M.Sc. and Ph.D. students as well as their tutors. Recently the role of the Symposium is to show the level of the Ph.D. and M.Sc. theses in different technical universities all over this country, and in particular at their electrical and electronics engineering departments as well as technical physics and mechatronics. Very high requirements to accept the papers for the presentation and the print in English and the participation of many international guests caused that the Symposium gathers only the best from these works. One of the biggest successes of this Symposium is that it gathers each year more than 100 relevant papers, from the M.Sc. and Ph.D. theses, which fulfill all the tough printing requirements in the international conditions. The Symposium slowly paves its way to be a nationwide and international forum of young researchers in the domain of advanced electronics and photonics. The Symposium has been publishing its work, since several years now, in the Proceedings of SPIE, USA. This year, the XVIth Symposium lasted a whole week from Monday till Sunday and gathered over 260 presentations and over 300 participants.
A lot of colleagues professors from the national academic centers is asking how it is possible to organize such a Symposium from the scratch and why it got such a success. One can try to name these factors, which seem to cause such an event very attractive for the young researchers.
It is comparatively difficult to present a work on WILGA Symposium. The presentation time is short. Only English is accepted. There are presented only the own research results. There are no parallel sessions. The work has to be preliminarily accepted by the student’s tutor. Each presentation is widely debated. WILGA offers to the young researchers the possibility to present their work in the newest branches of the science and technology. Such branches are clearly preferred during the following editions of the Symposium. There are organized topical sessions devoted to the most current research directions. The authoring sessions are invited and done frequently by the leading experts in their fields.
WILGA is organized under the most attractive umbrella. This organizational sponsorship is offered by the worldwide professional associations like IEEE and SPIE, international institutions like CERN, Geneva and DESY, Hamburg, and leading national institutions like the Committee of Electronics and Communications of Polish Academy of Sciences, Association of Polish Electrical Engineers, Association of Polish Mechanical Engineers. This group of institutions is joined by the technical universities from Warsaw, Białystok, Wrocław, Łódź, Kielce, Gdańsk, Lublin, Opole, Rzeszów, Szczecin, Poznań – which sent the largest number of students and young researchers.
It is comparatively difficult for a young researcher to publish a paper in WILGA Proceedings. The Proceedings are published abroad in a form of a book. The papers are peer reviewed. There is accepted 50% of the presented papers on the average.
WILGA gathers many young people from distant places in the country and from abroad. There is a possibility to compare personally the work conditions and research topics in different academic centers.
WILGA is unbelievably cheap and convenient. There is no comparable conference in this respect in this country. WILGA offer a lot for low price. There is no conference fee. There is a full social service – night and food on the modest but acceptable level. The fourth meal is served each day late at night, and is customarily sponsored by the IEEE – Poland Section.
WILGA is very diligent. The sessions last from early in the morning till late at night. There is organized an after supper night session lasting till 10 P.M. The fourth meal is served at a grill after this session.
WILGA bases solely on the voluntary work of the organizers and participants. The whole work is done by the students for the students. The students do the registration of participants. They organize the Symposium web site. They p[prepare the materials for print. The core of the work is done by the PERG/ELHEP ISE WUT Laboratory members and the SB IEEE members. However, they try to distribute the work among all interested participants.
WILGA is organized only by electronic media. There is not even a trace of traditional organizational methods. There are no invitations. The paper is not used at all. The whole information exchange is online over the net. A simple web site is http://wilga.ise.pw.edu.pl The major mail contact box is photonics@ise.pw.edu.pl
WILGA has no solid and permanent structures basing typically on the human relations and importance of people in the research world. The young researchers receive this feature as a very positive. The Program Committee is created exclusively during the Symposium, only from the present in WILGA senior researchers and tutors.
WILGA seems to base on the three simple and positive activity motifs of the young people: 1-Have Fun, 2. Have More Fun, 3-Learn a lot. The English expression ‘have a fun’ is here a mental shortcut for such feelings of young people as eagerness to get acquainted with other young researchers being in the similar life situation, willingness to participate in a real scientific symposium (for a number of them this is the first meeting of this kind) and the research curiosity of the world.
The XVIIIth IEE-SPIE WILGA Symposium 2006 will be held on 29 May – 4 June, during the week after the National Microwave Conference MIKON (which takes place every second year). We invite warmly young researchers and their tutors to WILGA on the Vistula River to the Resort owned by the Warsaw University of Technology.
A lot of colleagues professors from the national academic centers is asking how it is possible to organize such a Symposium from the scratch and why it got such a success. One can try to name these factors, which seem to cause such an event very attractive for the young researchers.
It is comparatively difficult to present a work on WILGA Symposium. The presentation time is short. Only English is accepted. There are presented only the own research results. There are no parallel sessions. The work has to be preliminarily accepted by the student’s tutor. Each presentation is widely debated. WILGA offers to the young researchers the possibility to present their work in the newest branches of the science and technology. Such branches are clearly preferred during the following editions of the Symposium. There are organized topical sessions devoted to the most current research directions. The authoring sessions are invited and done frequently by the leading experts in their fields.

A large-aperture, long-pulse XeCl excimer laser has been used to generate a soft-X-ray plasma source. Several laser optical configurations have been employed to optimise X-ray emission, including positive-branch unstable resonators and injection by seeding the gain region of the laser with a small commercial excimer laser, resulting in power densities in the range 10^12–10^14 W cm−2. The characteristics of the plasma source for each different laser configuration and for different target materials are investigated. The most suitable source conditions (spectral energy distribution, time duration, etc.) for specific applications are discussed.

Fiber lasers have the advantage of high beam quality, high efficiency, small size, and air cooling therefore much interest in the development of high power fiber laser systems have arisen recently in the world [1]. Almost every commercially developed fiber laser with nanosecond pulse duration, that are being used for material processing, are Q-switched systems. Vital parameters in the material processing such as repetition rate, pulse energy and pulse duration are correlated with each other therefore cannot be adjusted independently in the Q-switch mechanism. Pulse energy should be 0.5-1 mJ (for high beam quality) and as the repetition rate determines the processing speed, aiming for high average power leads to best results [2]. Therefore, all-fiber laser systems with high energy, high repetition rate (at high average power), whose parameters are to be adjusted independently and having diffraction limited beam quality are still needed.
In this study, ytterbium doped all-fiber laser amplifier with 60 W average power and more than 20 kW peak power at 1 μm wavelength was developed. This master-oscillator power-amplifier (MOPA) architectured system is composed of pulses, produced by electronically pumped diode, and amplified by a series of fiber amplifiers. Apart from Q-switch lasers, MOPA architecture allows us to adjust pulse duration, repetition rate and power independently. Beam quality is nearly diffraction limited, and typically the value is M2< 1,3.
