Influence of the gas stream velocity on the output power of gas-flow lasers excited by fission fragments of uranium nuclei

A model is proposed for gas-flow lasers excited by fission fragments of uranium nuclei. This model describes the dependence of the active lasing volume on the density of the gas mixture, on the velocity of the gas stream, and on the pump power. Calculations based on this model are in satisfactory agreement with the experimental time characteristics of the output pulses.
