Abstract

Studying the optimum performance of molecular lasers requires information.on active medium parameters. Those in case of laser are translational and vibrational temperatures T, T1 , T2, T3' , and lasing molecule concentration., n. Vibrational temperatures have previously been determined in series investigations of electro discharge CO—laser active medium234S. But definition of concentration n potentially associated with large errors due to lack of lower laser level's vibrational temperature T1 measurements. Other temperatures have been estimated according to approximate model. As it was theoretically shown6 , to determine the inverse medium parameters without simplification, one should measure the small signal gains for lines of (0001_1000) and (0001_0200) traditional CO2 bands, (0002_1001) second sequence band and (O1'l-ll'O) hot band. Translational and vibrational temperatures and lasing molecule concentration were defined for CO—laser using the small signal gain measurements and theoretical scheme6.
