Theoretical model of a radiation-frequency-discharge-pumped CO laser

The theoretical model of a radiation-frequency-discharge-pumped CO laser is described. The model consists of a block for calculating the spatial characteristics of a capacitive radiation-frequency discharge along the interelectrode distance and the distribution of the translational temperature of the gas. Another block contains the equations of the vibrational kinetics and the condition for stationary lasing in the resonator. The model was used to calculate the energy and spectral parameters of the CO laser in the stationary regime for different temperatures of the walls and two different spatial intensity distributions. The results are compared with the experimental data reported in the literature.
