Abstract

The CO-laser is generated by the exitation of an CO:N2:(He:02:C3H4) gas mixture cooled to T=100 K, N=0.5 Amaga. The discharge is initiated by a short pulse (t < 1 μs) of a hard UV-radiation. The laser efficiency runs to 12%. The energy consumed by a direct photoionization is 30% of the energy contribution to the volume discharge. The optimization of the photoionization pumping system parameters is examined. The dynamics of the recovery of an optical homogeneity of an active medium after the photoionization and discharge pulses is studied. The methods for improving the energy effectiveness of the photoionization CO-laser are proposed. The generation duration is shown to be adjustable within 2-600 μs, depending on the choice of a gas medium composition. The absence of helium in a gas medium deteriorarates but little the energy characteristics of the photoionization CO-laser.
