中文摘要：

在随机的媒介的激光现象在随机的媒介为光波基于局部性的理论被学习了。在随机的 Iasing 模式和局部性的模式之间的关系被直接经由有限差别时间领域方法数字地解决麦克斯韦方程调查了。空间分发和局部性的模式的系列为被动、活跃的随机的媒介被获得。结果证明随机的 Iasing 模式直接在随机的媒介内从局部性的模式发源。面对获得，局部性的模式的任何人能被放大并且能用作随机的 Iasing 模式。

英文摘要：

Laser phenomena in random media have been studied based on the localized theory for lightwave in random media. The relationship between random lasing modes and localized modes has been investigated by directly solving Maxwell equations numerically via the finite difference time domain method. The spatial distribution and the spectra of localized modes are obtained for both passive and active random media. The results show that random lasing modes directly originate from the localized modes inside the random medium. In the presence of gain, any one of the localized modes can be amplified and can serve as random lasing mode.
