Whispering gallery mode (WGM) microcavity is an efficient laser resonator, which can trap light in a rather small space, achieve a high light energy density and greatly enhance a light-matter interaction. Among numerous materials, rare-earth (RE) element ions doped nanocrystals-in-glass composite (NGC) can be used as an ideal candidate for WGM microcavity lasers due to its superior optical properties of crystals and outstanding mechanical processing properties of glasses. However, a few works on WGM microcavity lasers based on RE-doped NGC are reported. In this review, the basic principle and characteristic parameters of WGM microcavity were briefly described, and recent development on the WGM microcavity lasers made of RE-doped NGC was summarized. In addition, the corresponding future development was also forecasted.
