CO2 Laser: Flexible, Reliable and Approved Device Initially CO2-lasers thanks to their reliability, profitability and security proved to be a “workhorse” for industrial macroapplications. With the origin of diffusion cooling technology it became possible to increase CO2-slab-lasers power up to 8kW and CO2-lasers penetrated the whole range of laser industrial applications. The second part of this survey is devoted to the performance of laser dicing and welding.

High Resolution PhotoPlotters for Polygraphic Industry and Phototemplate Production Processing methods and information transmission mode determine the performance of polygraph high resolution equipment. Hardware in-house development in some cases becomes unprofitable and increases end product time-to-market. But emphasis on maximum use of unified blocks that are presented at the market gives the product functional flexibility. This article provides analysis and reasonable photopotter I/O interface throughput specification.

Dynamic Skin Cooling System for Cosmetology
M.Vasilyev, V.Djurba, V.Mit’kin, V.Romanov, A.Shepkin Demand for aesthetic services is around since ancient times. Now introduction into these services laser medicine technologies is evident. Laser emission absorbing effect triggers many physico-chemical processes in the biotissue. In the case of laser cosmetic procedures skin surface must be cooled. A controlled dynamic skin cooling system that is challenging for laser cosmetology is proposed.

Tunable Single-Frequency Semiconductor Lasers Lasers for communication links with channel wavelength-division multiplexing are presented. Single-frequency lasers with distributed Bragg mirrors successfully combine capability to generate narrow line (not more then 10kHz) emission and dynamic stable operation mode. Temperature methods for smooth and discrete emission wavelength tuning in the 635 to 1650nm range are discusse.

Silver sols optical properties in the process of their clustering Composite materials with metal nanoparticles as a non-linear optical medium are very attractive for creating integral optical devices and high speed optical switches. Metal (Ag, Au, Cu, Pt, Pd) hydrolysis, that are suspended in water small dimension (d<1µm) particles, interest many optoelectronic devices developers. In this article investigation of optical properties of silver nanoclusters that were obtained in the process of their clustering relations dependence on their structure and concentration are presented.

Gas Discharge Devices Airtightness and Internal Gassing Evolution The multistage technologic process for producing vacuum gas discharge devices (GD) requires constant control their airtightness. Reactive surface layers of internal elements adsorb gases, that latter begin to excrete. Some times it is difficult to separate internal gassing from the atmospheric gases in leakage that gives evidence of GD airtightness upset. This article describes a spectral analysis method that permits to separate these two processes.

Discrete-Linear Parametric Conversion in Atmospheric Photometry Solar radiation and cosmic rays cause ionization and recombination processes in ionosphere, that are important for creating thunder and mesosphere silvery clouds. Active launches of missiles with hydrogen-oxygen rocket engines that bring vapor to the mezosphere stir up interest in these clouds.

Designing Office Buildings with approach to Illuminating On one side monitoring illumination of modern business buildings is associated with providing comfort and work performance, from the other side it must respond to owner’s goal to decrease energy expenses. On behalf to what extent office floor space and its lighting systems adapt to lessee’s desire depends profit. The story about how to achieve maximum profit from every square meter of the office building washed with sun dates back to XIX century.
