Solution-processed halide perovskites have been demonstrated to exhibit many unique and excellent optoelectronic properties as novel optical gain media with wide color tunability. Compared with the bulk counterparts, the micro- and nanostructured perovskites exhibit more superior optical properties, such as the higher quantum yield, efficient carrier/photon confinement with higher optical gain coefficient, higher quality factor, lower threshold, and higher photo/thermal stability. These excellent properties highlight the importance and potential of perovskite micro- and nanolasers as the gain media for the development of new-generation on-chip semiconductor lasers. This chapter introduces the fundamental photophysics, carrier dynamics, unique optical properties, light-amplification mechanisms, and size/cavity effects in these perovskite lasers with micro/nanostructures. Recent advances of perovskite lasers with various types of micro/nano gain media and cavities are systematically presented.
