Continuous chemical HF laser with a modified radially expanding nozzle unit

We have determined experimentally the energy and spectral characteristics of a supersonic continuous chemical HF laser (oscillator) with a modified radially expanding nozzle unit operating according to the “nozzle–injector–injector” scheme of mixing reactants based on a new method of obtaining oxidizing gas. The practical realization of measures to decrease the heat loss and the loss of fluorine atoms, as well as the optimization of the mode of operation of the modified laser, permitted a 30% increase in its radiation power compared to the base oscillator equipped with a nozzle unit operating according to the “nozzle–injector” mixing scheme. Ways of further enhancement of the energy characteristics of the HF laser radiation are proposed.
