Tens to hundreds of output high power lasers from ICF (inertial confinement fusion) device, generally need to propagate through a long air path before they reach the target chamber. During the process, interaction between the high power pulse laser and air molecules emerges. Once the SRRS (stimulated rotational Raman scattering) threshold was reached, the SRRS effect would result in the loss of laser energy, the decrease of laser beam quality, or unable to reach the target. Further the transmitted laser would enter the multipliers as fundamental beam, then the conversion efficiency of triple-harmonic would be affected, even cause the destroy of frequency multiplication crystal. In order to improve the output ability, beam quality and control ability of the ICF high power laser drive, ultimately achieve the fusion ignition success, the SRRS effect must be suppressed. Based on SRRS four-dimensional mathematical model which conforms to current ICF experiment conditions, the longitudinal and horizontal rules of SRRS effect on ICF laser drive beam with the variation of pump light distribution on space was obtained. The research provided a support for the parameters choice of ICF laser drive and the optimization of output beam quality.
