Ki. Arshinov et al., CALCULATION OF THE VIBRATIONAL TEMPERATURES AND POPULATIONS OF THE LASER-ACTIVE LEVELS OF CO2 FROM THE SPECTRAL DISTRIBUTION OF THE GAIN, Quantum electronics, 28(8), 1998, pp. 659-662
The gains measured at the centres of vibrational rotational lines of t
he main bands of the CO2 molecule were used to determine, by the least
-squares method, the populations of the laser-active levels and the vi
brational temperatures of the active medium of a cw electric-discharge
CO2 laser.
