Laser

Abstract

There exist solid-state lasers whose working bodies have the shape of cylinders of different diameters. But when operating in the periodic mode and with intensive cooling of the surface of the active element, a thermal lens is formed in the rod, causing the outgoing radiation to increase in divergence, which can lead to malfunctioning of the active element. The purpose of the invention is to increase the allowable repetition frequency of the radiation pulses, that is, to increase the mean laser radiation power and to narrow its radiation pattern. Keywords: Frequency, Solid state lasers, Pulses, Patents, Russian translations.
