The “defects” on optics is the main limiting factor in enhancing the power of a high power solid-state laser system. This paper established a “defects” model about amplitude modulation based on statistics. Aimed at the booster of SG-Ⅲ prototype, the relationship between characteristic parameters of the model and the near-field quality of the beam was studied. The results show that, both the increase of total density of “defects” and the decrease of power exponent can cause the degradation of beam quality; for median-high frequency, different total densities of “defects” have approximately equal effects, while the effects of different power exponents vary; the larger “defects” can lead to more serious degradation of beam quality; for the booster, it is necessary to control the to
