Abstract

Disordered systems that both scatter and amplify light are currently attracting a lot of attention. The fluorescence from such a system shows remarkable spectral and temporal emission characteristics that are also observed in multimode lasers. However, there is no external cavity present. Light propagates diffusively in these so-called “random lasers”. Emission starts with a spontaneous seed, which is amplified as it stimulates emission while diffusing through the gain medium.
