摘　　要：综述了随机激光器的最新理论与实验进展 ,对光散射理论、环形腔理论、环形波导理论等各种随机激光理论的内容、应用范围及其差异等进行了重点分析和评述 ,并介绍了一些随机激光器的重要实验 .讨论了随机激光器未来的发展 ,并描述了随机激光器潜在的应用前景 .A detailed summary of random lasers in disordered gain media is presented, including recent experimental and theoretical developments. We lay particular stress on the various theoretical descriptions of random laser light as well as their differences, such as the theory of light scattering, ring optical resonators, ring waveguides and so on. Some important experiments following the development of these theories are also mentioned.Future directions for the development of random lasers are discussed, and potential applications of the ZnO random laser are also described.
