Original Abstract

Since their initial demonstration, random lasers have attracted a lot of interest due to their complementary characteristics compared to conventional lasers [1]. In a random laser, the light is trapped by multiple scattering in the gain medium, which has been demonstrated in different kinds of materials, ranging from grinded laser crystals to polymer films and ceramics. Recently we demonstrated [2] random lasers at terahertz (THz) frequencies by making use of quantum cascade laser (QCL) active regions, resulting in broadband surface emission with a highly collimated output beam
