Abstract
In recent years, random laser has attracted much interest and attention [1, 2]. Unlike a conventional laser, its cavity is formed by multiple scattering and localization of light in a disordered gain medium. It has been widely studied by a number of groups because of its important scientific implications and high potential technological applications, such as the understanding of light transport and localization in active random media, micro- and nano- lasers, laser paint, light emitting devices, and 3D display. Random lasing actions were mainly demonstrated in near ultraviolet and infrared region. Recently, blue-light-emitting random laser action with coherent feedback was observed in ZnSe particles [3]. However, the research of green-light -emitting random laser has not been reported to our knowledge.
