Light sources

Light sources

A laser is a source of monochromatic coherent radiation with a high-directivity light beam (from the English "LASER"  - Light Amplification by Stimulated Emission of Radiation).

An optical quantum generator is a device that converts pumping energy (electrical, chemical, light, heat) into monochromatic, coherent, polarized and narrowly directed radiation flux.

Classification of lasers is fulfilled according to:
  • The pumping method (the method of creating an inverse population) - optical, chemical, excitation by electron impact, etc .;
  • The type of operation medium - glass, liquids, gases, crystals, semiconductors and others;
  • Type of resonator;
  • Operating mode - continuous or pulsed;

These differences are determined by  the practical application of radiation sources.


The scope of radiation sources today is very wide. Since the study of the radiation interaction  with matter is of scientific interest, lasers are actively used in fundamental chemical, physical and biological research.

Optical quantum generators found their applications in such industries as:

  • Military industry;
  • Medicine;
  • Laser processing of materials (cutting, welding, engraving, marking, hardening);
  • Instrumentation;
  • Engineering;
  • Textile industry;
  • Food industry.
