Numerical investigations of energy characteristics of the first overtone generation of a high-power supersonic e-beam-sustained CO laser

For operating conditions of the high power supersonic e-beam sustained CO laser a numerical investigation of the energy and spectral characteristics of the first overtone generation is conducted. It is shown that electro-optical efficiency of the first overtone generation can be more than 30%. The efficiency of a spectrum selection both on fundamental and first overtone transitions is evaluated. On the basis of numerical calculations the engineering evaluations for several variants of such a device are executed.
