Abstract

A study was made of a laser based on a chain reaction of fluorine with hydrogen (deuterium) initiated by powerful light sources and operating in the amplifier mode. The conditions for reaching a near 100% energy efficiency of the amplifier at an active mixture length up to approximately 6 meters were determined experimentally. Spectral characteristics of the laser radiation were investigated thoroughly. The tolerable extent of difference between the actuation time of the master generator and amplifier was determined. A possibility was demonstrated to attain a low radiation divergence.
