摘要：

A narrow-band BOXCARS system has been used for spatially resolved diagnostics of a microwave discharge in an axial-flow CO2 laser module. Axial and transverse distributions of the vibrational and rotational temperatures of N2 and CO as well as those of the CO2 dissociation degree have been determined. They have been used as a reference for a vibrational kinetics model for the laser medium. This allowed determination of an approximate electron density distribution along the discharge tube. A CCD camera has been used for visualizing the intensity distribution in the beam overlap region and checking its effect on the CARS saturation behaviour.
