Study on the properties of an inverse medium in a plasmatron channel

The existence of non-equilibrium energy distribution by oscillating and advance degrees of molecule freedom in peripheric zones of discharge stabilized by the blow-in of N2:CO2:He gas mixture through porous walls of the discharge channel in (1-5)x105 Pa pressure range and 20-150 A current range is experimentally shown. Amplification factor of the sound laser irradiation at 10.6 μm wave length for different currents, pressures and component rate is measured. The highest value of the a=4 m-1 amplification factor is obtained for the 56N2:5CO2:39He mixture with the I=60A current
