Effect of the optical quality and gain characteristics of the active medium of a HF-excitation electric-discharge amplifier on radiation parameters in the zone of application

The results of investigation of the simultaneous effect of the optical quality and amplifying characteristics of the active medium of a pumped-through HF-excitation CO2-amplifier are presented. The amplitude front of the light wave was restored by the measured distributions of the small-signal gain and the phase front —from the results of processing the holographic interferograms of gas flow.
