An experimental investigation was made of lasing of an optical-breakdown plasma in an He--Xe gas mixture exposed to CO/sub 2/ laser radiation. A wide range of pump pulse energies and durations and active mixture pressures was used. Lasing was realized on four Xe I transitions (lambda = 2.03, 2.65, 3.4, and 3.65 ..mu..). The pump pulse duration was found to exert a strong influence on the lasing characteristics of the optical breakdown plasma. An analysis was made of the role of gasdynamic processes in the interaction of the CO/sub 2/ laser radiation with the gas close to a target during the buildup of inversion. A quasi-cw lasing regime of the recombination laser in the optical breakdown plasma was observed.
