Symposium Renewable Energy Sources 2013 Renewable energy sources which are destined to become an alternative to the traditional hydrocarbon sources will hardly be able to take the leading position at the energomarket. Although the structure of energy balance will change with the development of renewable energy sources the absence of reliable energy storage systems will prevent their active implementation. German experts told about that and about what the "island solutions" are. They shared their experience of success and mistakes in solution of the issues of solar power engineering.

New laser strategy of COHERENT company The purpose of our participation in this exhibition is presentation of COHERENT’s new strategy. COHERENT is one of the world’s oldest laser companies. It was established in 1966, only five years after invention of the laser. During many years, Approximately from 2000, we began to focus more attention to industrial applications of lasers, to their use the industry for different materials processing purposes.

Investigation of Particle Spectrum Characteristics originating at Uultrashort-Pulse Lasers Duty The ultrashort-pulse laser provides a precision and quality that have been previously unknown. This is a fact. And because of new applications, this relatively young technology is becoming more and more established in industry. What has been mostly ignored, however, is the question of which particles are entering the environment through the use of this laser. ULT has got to the bottom of this issue.

High Energy Thin Disk Laser Technology The disk laser was invented more than 20 years ago by Dr. Adolf Giesen and his coworkers at the University of Stuttgart. Disk laser technology is beneficial for medical applications, micro- and macro machining in the industry, as well as for such research fields as optical parametric chirped-pulse amplification, extreme ultraviolet generation, attosecond physics.

He-Ne Laser with Non-Traditional Active Component A cylindrical active component is traditional for the He-Ne and other gas-discharge lasers. The form of gas discharge and easiest fabrication technique determine its choice. However, more than 40 years ago He-Ne lasers with elliptical and rectangular cross-sections started to be researched and even produced by the industry. At the same time the publications on active components with the changeable longitudinal geometry occurred. But the industry did not respond to them. In our report we are going to show that apparently it was an error which should be corrected.

High-Sensitivity Selective Optical Chemosensor Based On Photonic Crystal Lattice Deformation Anisotropy The use of photonic crystals as sensors is based on the change of their spectral characteristics on exposure to various analytes. A new approach based on a recently discovered asymmetry in deformation of the photonic crystals lattice allowed to create cheap, high-sensitive and fast chemosensors which do not require spectral instruments. This effect shows itself most strongly in gaseous ammonia. The sensitivity of such a sensor is several parts per million (ppm), while the response to an increase in concentration is less than 200 ms.

Coherent Emission from Carbon Nano-Tubes In this paper, the experimental results of coherent emission production with carbon nano-tubes synthesized in carbon, heterogeneous plasma and doped with metal additives are discribed. The results are in good agreement with the theoretical conditions for the occurrence of the Dicke effect.

Laser Locators For Helicopter Flight Safety Improvement In case of helicopters poor visibility at low light conditions artificial vision channels can not provide piloting safety. Electrooptical surveillance systems can’t always detect and visualize separate low-contrast hazards that appear at low-altitude missions (electric supply chains, masts, tubes, trees etc.). Laser locators operation is based on the principle of superposition laser scanning (sensing) space signal and background television or thermal image received on helicopter course. The article considers conditions and methods of application of laser radar systems as a part of helicopter avionics complexes.

THz Photometers for Solar Flare Observations From Space The first detection device conceived to observed solar flare THz emissions on board of stratospheric balloons has been developed. It is intended to determine the still unrevealed spectral shape of the mysterious THz solar flares emissions The system, named SOLAR-T, has been built, integrated to data acquisition and telemetry modules, and tested. It utilizes two Golay cell detectors preceded by low-pass filters, 3 and 7 THz band-pass filters, and choppers. SOLAR-T can detect relative temperature variations smaller than 1 K with sub second time resolution. The experiment is planned to fly on board of two long-duration stratospheric balloon flights over Antarctica and Russia in 2014–2016.

Problems of Remote Oblique Spectroradiometric Sensing In case of forest area structures remote oblique sensing their appear trapezoidal scan frame distortion, that decreases the spectroradiometric system operation speed. It’s proposed to use liquid crystal spectral filters with electronic bandwidth control. The optimal filter mode during the frame is theoretically justified.

Improving the Hermetic Seal on Moxtek’s AP3 Window Moxtek is a leading manufacturer of X-ray windows for low energy X-ray detection. Moxtek manufactures ultra-thin polymer X-ray windows that are attached to metal mounts which house energy dispersive X-ray detectors such as Silicon Drift Detectors (SDDs). These windows allow for transmission of low energy X-rays while maintaining a hermetic seal critical for the X-ray detector’s performance. It is well known that no material is a perfect gas barrier and gasses will diffuse through window assemblies over time. Were showing the results of the analysis of hermetic seal of structure X-ray windows after the processes of chemical and plasma purifications.
