测量了不同能量的光束,通过不同长度的水介质在窄线宽与宽线宽两种情况下的衰减系数,研究了受激布里渊散射对激光在水中衰减特性的影响.结果发现,激光光束在水中传播时的衰减系数与激光光强和线宽有关,而不是通常情况下所认为的常数.还从理论上进行了分析.
The effects of stimulated Brillouin scattering on the attenuation characteristics of laser in water were studied by measuring the attenuation coefficients of aqueous media with different lengths under the conditions of narrow linewidth and wide linewidth.The results show that laser The attenuation coefficient of the beam propagating in water is related to the laser intensity and the linewidth, not the usual constant, and is theoretically analyzed.
