Abstract

In this study, a physical model of the supersonic flow chemical reaction and beam transmission in the laser cavity is established, and a numerical calculation is carried out based on the multiphysical field coupling method. The results show that the mismatch between the wall morphology and aerodynamic parameters is the main reason for the excessive power density of the laser spot. Furthermore, according to the calculation results, the surface type of cavity was optimized, and the near-field uniformity was effectively improved. The research results will provide a theoretical basis and design reference for chemical laser engineering applications.
