The simulation of the influence of laser atmospheric transmission is of great significance to the practical application of various lasers, which can provide an important guarantee for the smooth development of laser practical tests. Inthis paper, the simulation of the effects of atmospheric attenuation, turbulence and thermal halo on laser beamsin laser atmospheric transport simulations and related work are mainly introduced. In terms of atmospheric attenuation, it is usually necessary to calculate the atmospherictransmittance, and there are mature simulation software. For atmospheric turbulence, there is currently a phase screen method can be equivalent to phase and refractive index perturbation to simulate random turbulence, laser beam transmission simulation in turbulence, cannot actually simulate turbulence. In terms of atmospheric halo, most scholars have only carried out steady-state thermal halo researchbecause of the randomness and transience of the thermal halo. Laser atmospheric transport simulation also needs further study in the coupling of turbulence and thermal halo, the joint establishment of a simulation system for linear and nonlinear effects, and the construction of a laser atmospheric transport simulation platform.
