Manufacturing stainless steel and copper alloy bimetallic structures with the aid of domestic plant KLP-400 made at the small-scale enterprise PC “Moscow Center of laser technologies” of Bauman STU of Moscow for coaxial laser fusion is considered. A metallographic analysis of the structure of samples grown and which has shown high structural-sensitive properties is carried out.

Возможности прецизионной микрообработки материалов импульсным излучением лазера на парах меди Source", 2a, Vokzalnaya Str., Fryazino, Moscow Region 141190) Possibilities of precision material micro-processing by laser pulse copper-vapor radiation -table 150x150mm for the thin-sheet material micro-processing -0.3-0.5mm and 0.6-1mm. The productivity of the plants mentioned as compared with common methods including also EEM is by an order and more higher. Material micro-processing with laser nano-second copper-vapor radiation ensures a higher quality of a cut: minor roughness of a cut surface (≥1…3µkm) and the area of thermal impact (≤3…5µkm) and stratifications and micro-cracks do not appear in such heat-resistant material as molybdenum and tungsten. The paper reports the results of experimental researches on microprocessing by laser copper-vapor radiation with wavelengths of radiation in the visible spectrum region of 510.6 and 578.2 nm and the frequency of pulse repetition of 14-15kHz, a nano-second duration of pulses and a peak power density of 109-1011 W/cm 2 in the focused spot light with the diameter of 10…20µkm. The investigations carried out became a basis for the creation of modern automated laser technological plants "

As a result of the experimental investigations carried out on the dimension processing of carbon plastic of 3mm thick with the matrix on the basis of epoxy resin by continuous emission of the fiber ytterbium laser with λ=1.06 mkm of the wave length there are defined basic technological parameters ensuring high quality and processing speed. A comparative investigation of the processing method impact upon mechanical strength of samples investigated in accordance with RSS 33375-2015 is carried out.

Photo-acoustic substance homogenization for optical measurementsTheoretical and experimental investigations of photo-acoustic effect use for the homogenization of dispersion particles with the purpose of spectral measurement accuracy increase are shown.
