摘要：
The results of experimental studies of the formation of narrow-band high-energy radiation in a discharge single-module KrF laser are presented. The conditions for the combustion of a diffuse discharge in a KrF laser are revealed, which provide a maximum specific energy of radiation pulses of 9.5 J/l, with an internal energy efficiency of similar to 4%. The duration of radiation generation for several half periods of the pump current is realized. The operating conditions of the optical system generator-amplifier allowing narrow-band (2 pm) high-energy radiation in the spectral range of 247.5-249.6 nm are determined.
