Lead halide perovskites are considered as very promising photovoltaic materials due to their tunable direct bandgaps, large absorption coefficients, long carrier diffusion lengths, and ultralow trap state densities, etc. With these unique properties, the lead halide perovskites have also demonstrated great potential for use as semiconductor gain materials. In this review, a snapshot on the recent advances of lead halide perovskite micro‐ and nanolasers is given. The dependence of lasing performance on the perovskite dimensionality, crystal size, and operation temperature is systematically discussed. Furthermore, the development of continuous wave (cw) pumped perovskite lasers and lead‐free perovskite lasers is also summarized. In the final section, the challenges and future prospects of metal halide perovskite lasers are provided. These pieces of knowledge would help advancing the development of perovskite on‐chip coherent light sources.
