Some Tasks of Modern Laser Technologies

The efficiency of drilling and cutting of metals by laser radiation under the influence of two lasers, during processing in water and drilling of small holes in ceramics and metal with a high aspect ratio has been determined. The conditions for clearing the channel of laser radiation propagation through the flame of burning hydrocarbons, as well as high-quality welding of two identical tapes made of polymer composite materials for several types of tapes have been found. Diamond coatings on a cutting tool made of VK8 hard alloy in the plasma of a laser plasmatron have been obtained, and diagnostics of the plasma and coatings has been carried out. A two-wave pyrometer based on a spectrometer with a diffraction grating for measuring the temperature of a heated surface has been developed.
