REFLECTIVE TYPE LASER AMPLIFIER,

Abstract

Calculations have been carried out in an analysis of a reflection type laser amplifier. Electromagnetic radiation is assumed to travel at normal incidence through a system composed of air, a partially transmitting silver reflector, active media such as ruby, and a thick silver reflector. The analysis is facilitated by considering the ruby as a medium with an effective negative conductivity resulting in the growth of the wave during propagation. Highest gains are obtained with the front mirror completely removed, since losses resulting from a skin effect mechanism cut down the useful power output. In the system consisting of air, ruby and metal, the presence of the rear metal reflector decreases the attenuation factor required for maximum gain to almost half the value required for a completely transmitting system consisting of air, ruby, and air.
