Determination of the gain of molecular lasers from the characteristics of incoherent IR radiation
Abstract
A method is developed for determining the gain of CO2 gasdynamic lasers from the characteristics of incoherent IR radiation in the 4.3 and 2.7 micron vibration-rotation bands. The method can be extended to polyatomic molecules, the upper and lower levels of which belong to two different modes, the vibrational distribution within each mode being of Boltzmann type. Results are presented for a 0.1CO2 + 0.4N2 + 0.5He mixture.
