【摘要】 讨论了相干反馈无序激光器中两种多重光散射:构成回路的多重光散射和不构成回路的多重光散射。构成回路的多重光散射产生激光“种子”,并且少粒子构成的回路比多粒子构成的回路更易激射。不构成回路的多重光散射增加了激光在增益介质中的路程,使激光增强,并使激光沿各个方向发射。更多还原

【Abstract】 Investigate the two kinds of multiple scattering in random laser with coherent feedback:the multiple scattering which forms loop and which doesn’t form loop. The multiple scattering which forms loop can produce "seeds" for laser,the lasing probability is more in the loop which contains fewer particles. The multiple scattering which doesn’t form loop can increase the mean free path, thus enhancing light amplification , and making laser in various directions. Our viewpoint is in agreement with the experiments.更多还原
