当介质的吸收系数超过临界值α cr时，瑞利散射是主要的受激散射过程。结果表明，瑞利散射的瞬态增益是与受激布里渊散射竞争的重要因素。入射激光脉冲的初始斜率（而不是峰值功率）决定了α cr的值。我们的研究结果与理论研究完全一致。
Rayleigh scattering is the dominating stimulated scattering process when the absorption coefficient of the medium exceeds a critical value α cr. It is found that the transient gain of Rayleigh scattering is important for the competition with stimulated Brillouin scattering. The initial slope-not the peak power-of the incident laser pulse determines the value of α cr. Our findings are in full agreement with theoretical investigations.
