Abstract
An earlier model developed by others to study the 10.6‐μm laser transition in CO2 has been extended for studying the 16‐μμ (0200)→(0110) laser transition in cold CO2. The rate equations take into account the rotational relaxation and collisional transfer of population among (0200), (1000), and (0220) levels of CO2. The model has been used to study the effect of various parameters on the 16‐μm output. It has been found that at higher pressures the collisional relaxation of the (0200) level can be overcome by application of a more powerful 9.6‐μm pulse to achieve an inversion between the (0200) and (0110) levels of CO2. It is predicted that if transverse excitation is used in these cold mixtures, pulsed powers in excess of 100 kW could be obtained on 16 μm.
