Abstract :
Simple expressions for the small-signal gain and the saturation intensity in a transverse-flow CW CO2 laser have been derived considering the effect of gas flow and the finite time required for N 2 molecule to transfer its energy to CO2 molecules. These expressions provide estimates of these parameters fairly close to the experimentally measured values in high-power transverse-flow CW CO2 lasers
