The study reports about investigation results, which are directed to the decrease of radiation pulse duration in small-sized sealed-off ТЕА-СО2 lasers. Minimal duration of laser pulses about a few nanoseconds with energy per pulse 50-150 mJ was achieved by increase of working laser mixtures up to 6 atmospheric and decrease of laser resonator length up to 25 cm. The aim of this work is investigation of main conditions at which laser pulses have durations in nanosecond range.

Key words: ТЕА-СО2 laser, optical resonator, volume discharge, laser energy per pulse, laser pulse duration.
