Abstract:

The phenomenon of compressed gas breakdown by CO2 laser emission is examined both theoretically and experimentally. It was disclosed that gas breakdown at high pressures p or 30 atm differs considerably from that at low pressures the threshold density of the emission flux and energy appear in the low pressure region as diminishing functions of p and in the high pressure region, conversely, they increase. The dependences of emission threshold density and energy in pressure are different for molecular and atomic gases.
