Abstract

Presented are the results of numerical simulation of autonomous chemical HF laser operating in a pulse-periodic mode with continuous pumping. To produce active medium, perspective HYLTE nozzles were considered that are notable for providing fast mixing of reactants within the lasing region. To simulate the reactants’ flow in the nozzles and the resonator cavity, a system of equations based on 3D Navier-Stokes equations was used. The performance parameters of this laser operating in a continuous-wave mode were also estimated and compared to the corresponding parameters obtained in case of pulse-periodic mode.
