Diagnostics of active media of CO2 lasers by the laser spectrograph method

Abstract

An analysis is made of the results of diagnostics of the active medium of a waveguide CO2 laser by the laser spectrograph method. It is shown that a simplified approach to this method has led to errors in determination of the translational and vibrational temperatures of CO2 molecules and, consequently, to an incorrect understanding of the physical processes occurring in the active medium of the laser.
