A mathematical model, describing the dynamics of laser plasma (gas dynamic stage) in air medium with the pressure variation in the range of 1-100 Bar, is presented. The simulation is based on the transient axially symmetric system of radiative gas dynamic equations. The application of the multi-group diffusion approximation to the simulation of radiation transfer is discussed. The solution of gas dynamic equations is made by the explicit finite-difference FLIC method. For the energy equation solved jointly with the averaged equation of radiation diffusion, the implicit difference scheme is used.
