Random laser is a small laser source observed in disordered gain media, in-cluding disordered solutions, semiconductor powder, nanostructured thin films, and so on. Random laser is special because it has no optical cavity, which is dif-ferent from conventional laser. Based on some advantages that random laser owns, it has been studied widely and deeply in recent couples of years. In this thesis, it mainly describes the research history, fundamentals, applica-tions, and experiments in our lab. Research history includes how random laser is discovered, and how it is developed. Basic theories of random laser are also ex-plained in this thesis. Random laser can bring people great benefits owing to the low cost, multidirectional light, changeable shape, and small size. It deserves to be studied and it will change many application areas. Finally, we did some experi-ments in our lab and the results helps us to understand the principles of random laser.
