Abstract : Simulation of the nonlinear effects of laser atmospheric propagation is reported in this paper. A set of atmospheric hydrodynamic equations and the nonlinear electromagnetic wave equation for interaction with the atmosphere are given. The wave equation describing small-perturbation instability induced by stimulated thermal Rayleigh scattering (STRS)is derived. Also, turbulence is theoretically treated. Based on these equations, we performed a set of 4D programs (TURBLM) to simulate thermal blooming and phase compensation for it, small-perturbation instability, and the interaction of turbulence with thermal blooming. The simulated results are in agreement with theory and experiment.
