PHYSICAL FOUNDATIONS OF LASER TECHNOLOGYFORMATION OF TYPES OF VIBRATIONS

Abstract

This topic discusses the physical foundations of laser technology and the formation of the types of vibrations that occur in it. The basic conditions necessary for the formation of a laser are considered - the energy levels of atoms and molecules, stimulated emission, population inversion, etc. It also provides an understanding of how various vibrations are formed: mechanical, electromagnetic and molecular vibrations, and what role they play in the operation of a laser. This topic studies the basis for the stability, narrow focus and high-frequency properties of laser radiation. At the same time, clear and understandable information is provided about the principles of operation of laser devices and their relationship to vibrations. The topic is theoretically important and of great importance in understanding practical laser technology.
