Lead halide perovskites have been very promising photovoltaic materials due to their unique properties, such as high absorption coefficients, long carrier diffusion lengths, and ultralow densities of trap states, etc. Very recently, the certified power conversion efficiency of perovskite solar cells has been increased to 22.7%, approaching that of crystalline silicon solar cells. As direct bandgap semiconductors, lead halide perovskites also show wide‐band tunable emissions with high quantum yield, which is important for numerous practical applications, especially for the “green gap” region of conventional semiconductors such as III‐nitrides and III‐phosphides. Consequently, versatile lead halide perovskite based micro‐ and nanolasers have been proposed and experimentally demonstrated in the past few years. This review discusses the recent advances of perovskite micro‐ and nanolasers. Following their fundamentals in light confinement and material properties, perovskite micro‐ and nanolasers have been categorized into six sections, i.e., pristine lasers, structured perovskite lasers, multiphoton pumped lasers, perovskite lasers with better stability, postsynthetic control of perovskite lasers, and perovskite laser arrays. At last, future prospects for perovskite lasers are provided.
