Two-dimensional model of an active medium of a fast-flow CO laser with state-to-state vibrational kinetics

A two-dimensional numerical model of the active medium of a fast-flow electron-beam-controlled CO laser, taking the latest achievements of state-to-state vibrational kinetics into account, is developed. The model includes detailed kinetics and spatial description of non-self-sustained discharge in the gas flow. Using this model the basic characteristics of two schemes of a gas-flow CO laser with subsonic and supersonic flow of the gas mixture are compared.
