Identification And Adjustment Of Geometric And Dynamic Errors In the areas of production, where we are talking about micro and nano-meter values, which include laser cutting, scribing, lithography, holography, 3D printing, additive technologies, etc., it is extremely important to ensure the stability and repeatability of geometric and dynamic errors in process time. In particular, the main parameters characterizing the quality of mechanical positioners are: precision, two-way repeatability, tracking error, and decay time. To obtain high-quality motion control and accurate product geometry, it is necessary to provide high-frequency selective current vector control, and to perform a selective calibration of static errors of the positioner. This article analyses one of the ways to reduce errors and improve the quality parameters of the positioner.

Modular Switched Mode Power Supply For Diode-Pumped Lasers The results of the research of the market of diode-pumped lasers revealed a sharp difference in the demand for power supply products of diode arrays between Russian and foreign customers. Taking into account these features based on the modularity principle, a compact pulsed power supply for mobile laser devices was developed. The power supply meets the requirements for lasers: increased power (over 5 kW), accuracy of current stabilization, small front and cut-off pump pulses (no more than 15–20 µs), reduced weight and size characteristics, and a wide range of operating temperatures. A new modular switched mode power supply for diode-pumped lasers greatly simplifies laser manufacturers to solve the problems of powering laser diodes and tuning drivers when assembling mobile laser systems.

Information Capacity Of Facet Optoelectronic Systems Modern microminiature digital photo and video cameras are built according to the principles typical for the facet eye of insects. The desire to increase the number and size of the pixels used by the photomatrix obviously has technological limitations that determine the information capacity of the system. At the same time, there are theoretical limitations of information capacity. First of all, these are diffraction limitations that determine the limit of spatial resolution for micro-optical systems. In addition, these are energy limitations related to the signal-to-noise ratio during exposure. In the article these factors limiting the information capacity of the system are considered and formulas are obtained that allow to determine the rational combination of parameters of the facet optoelectronic system and calculate its information capacity taking into account the noted limitations. The parameters of known foreign developments are close to those calculated by the above formulas.

0.97 And 1.94 Mkm Wavelength Laser Radiation Effect On The Oral Mucous Membrane Regeneration In The Experiment The article presents data on the peculiarities of the processes of regeneration of wounds of the oral mucous membrane of laboratory animals after exposure to laser radiation with a wavelength of 1.94 µm and 0.97 µm at various radiation powers. It is known that oral mucous membrane exposed to laser radiation is prone to coagulation necrosis and the subsequent inflammatory reaction of the tissue with destruction of the epithelium, mucous membrane and partially muscular tissue. It has been established that tissue regeneration and wound defect healing slows down with increasing power.

Optical Properties And Applications Of Germanium In Photonics Two windows of atmospheric transparency in the infrared (IR) region of 3–5 µm and 8–14 µm almost overlap with the region of maximum transmission of germanium (Ge). Ge is transparent in the 1.8–23 µm range (although a number of phonon absorption bands are present in the 11–23 µm region), there is also a transparency window in the terahertz (THz) spectral range (~ 100–300 µm). Due to its physicochemical properties, crystalline germanium is one of the backbone materials of IR photonics and its use amounts to 25–30% of the total consumption pattern of this material. The article provides an overview of the using of the material in photonics in depending on the thermoelastic stresses arising during crystal growth, impurity heterogeneity, and structural defects.
