Abstract
Time characteristics of the afterglow gain of a pulsed CO2:H2 laser amplifier were investigated. Evidence shows that a rapid nonradiative transfer of population from the upper to the lower CO2 laser levels occurs at higher H2 pressures (P ≥ 2 torr). An absorption pulse on the order of 1 msec in duration following the initial gain period is attributed to population accumulation (or a bottleneck) at the 0101 level.Keywords
