Abstract

When high power laser propagating through tens to hundreds of meters air path in ICF experiment, once beyond stimulated rotational Raman scattering (SRRS) threshold, the high power laser beam would be subject to loss of energy and a decrease in beam quality, even causing the optical components to be destroyed. In this paper we studied how SRRS process effects high power super-Gaussian laser, and made corresponding analysis of the lasers’ intensity distribution in near field. We settled the numerical simultaneous equations by finite element method of MATLAB. Finally the rule of SRRS effects on high power super –Gaussian laser’s beam intensity distribution in near field through air was obtained..
