Abstract

Optimum conditions for the efficient operation of a cw CO laser excited by transverse dc glow discharge using a gas mixture of CO/N2/He/02 has been investigated by computer simulation. The simulation model combines direct excitation process by electron impact, vibration to vibration ( V-V ) and vibration to rotation/translation ( V-R/T ) energy transfer process, spontaneous and stimulated emission process, and semi 1-dimensional flow model. One of the important experimental problems that the laser power output decreases against the increase in gas flow velocity is analyzed by the simulation. According to the computed results, the problem is not serious if the gas temperature is low enough or sufficient discharge current is applied. The possibility of the high power and efficient laser operation even at around 200 K is predicted by the simulation.
