Model of jet plasma flow with absorption of a CO$_2$ laser pulse

An approach has been developed and numerical simulation of the dynamics of an optical discharge plasma has been carried out on the time scale of absorption of a CO$_2$ laser pulse. The features of the propagation modes of optical discharges are taken into account: light supported detonation wave (LSDW) and fast ionization wave. A system of hydrodynamic equations with energy sources is used, supplemented by the calculated value of the integral parameter - the momentum caused by the microjet flow of the LSDW plasma. A comparison of the results of numerical modeling and visualization of plasma glow shows their close agreement when taking into account the microjet flow. Characteristic trends in the dynamics of the structure and parameters of the plasma in the microsecond range of the laser pulse are determined.
