Abstract
Investigation on stimulated rotational Raman scattering (SRRS) in air with high power laser to seek suppressionmethods is one of the key issues which needs to be addressed in the construction of high-power solid-state laser driver.The evolu-tion of SRRS with diverging beam is studied numerically.The threshold of the intensity-path-length product and the criterion tosuppress SRRS using diverging beam are established by geometric approximation.The results show that the effect of SRRS growsslowly in diverging beam,choosing proper divergence angle can suppress SRRS effectively,and the angle depends on the beamsize,laser intensity and propagation distance.关键词
