Influence of acoustic waves on the output power of pulsed gas discharge lasers

It was established that acoustic oscillations are excited in the active media of pulsed gas discharge lasers having high specific pulse input energies. It was also found that in the pulse-periodic regime the excitation of acoustic oscillations leads to a redistribution of the density of the active medium in the discharge tube, and this results in a resonant dependence of the average laser output power on the repetition frequency of the excitation pulses.
