The efficiency of a master oscillator-amplifier scheme and the possibility of its using in multichannel nuclear-pumped laser systems are studied. The small-signal gain and saturation parameter are measured for the He:Ar:Xe = 380:380:1 mixture at a pressure of 1 atm at a wavelength of 2.03 {mu}m. It is shown that the small-signal gain increases linearly with the specific pump power density and achieves 1.1-1.2 m{sup -1} at a pump density of 40 W cm{sup -3}. The saturation parameter is almost independent of the pump power and is equal to 70-90 W cm{sup -2}. It is found that at the pump-pulse maximum (40 W cm{sup -3}) the laser radiation power increases after amplification by 100%. (active media, lasers, and amplifiers)
