Abstract
To study the characteristics of high energy pulse laser propagating through turbulent atmosphere, the propagation of high energy laser in atmosphere was numerically simulated, and the far-field beam quantity in terms of the power in the bucket was compared with the experiment performed by using an Nd∶glass laser at output of 800J. The error between the numerical simulation and experiment was analyzed in detail. The numerical simulation and experiments were studied under different conditions of visibility, output energy, and turbulence. It is shown that the numerical simulation can be used to predict the experimental results by a suitable choice of structure parameters of the phase screen. The results show the significance to guide the application and development of high energy pulse lasers.
