Progress of Laser Technologies in Belarus

Abstract

A review is given of the main works in the field of laser engineering and technology aimed at devising and using lasers in medicine, microelectronics, for treatment of materials, and in instrumentation.

The characteristics of some types of lasers developed at research institutes, in design offices and companies (solid lasers, distributed-feedback crystals) are given.

The main fields of application of lasers in therapy and ophthalmology are considered. The parameters of a number of systems of laser medical equipment made in Belarus are given.

Specifications are described of some types of laser precision equipment for making products for microelectronics (pattern generators, laser sets for marking products of electronic and radioengineering industry, etc.). The characteristics are given of technological sets on the basis of solid-state and CO₂ lasers for treatment of materials (contour cutting, engraving, thermal treatment, sawing of diamond raw material, broaching of profile channels in diamonds and diamond-like materials).

In the field of devising instrumentation, the parameters of some types of lidars and complexes of equipment for laser detection and ranging of objects are given. In particular, laser systems for trajectory measurements of the flight of various objects, testing of radioelectronic devices, tank and artillery laser range finders, and laser systems of anti-tank shell control are considered.

The parameters of a number of laser crystals and components of laser equipment (active elements, dielectric mirrors, interference filters) made in Belarus are described.
