It is shown experimentally that gas density fluctuations ~ 1% affect strongly a plasma stability in an UV-preconized self-sustained discharge. The influence of gasdynamic disturbances created in a closed gas channel of a high-repetition-rate pulsed gas laser upon output laser performances was studied. The interaction between acoustic waves and a diffuse glow discharge plasma leading to appearance of the thermoacoustic instability was observed.
