Abstract
Over the past few years, there have been much interest and studies on random lasers. A random laser is different from a conventional laser in the feedback mechanism. A conventional laser consists of a gain medium and a cavity. The cavity, usually made of mirrors, provides coherent feedback for lasing. However, a random laser has no mirrors. The feedback is supplied by optical scattering in a disordered medium.
