Abstract

Abstract: Continuous‐wave (CW) operated lasers are regarded as a stepping stone to the development of electrically driven lasers and crucial for practical application in high‐density integrated optoelectronic devices. Recently, metallic halide perovskites are demonstrated as excellent gain materials for CW lasers owing to their large optical absorption coefficient, low defect density, long diffusion length, and suppressed Auger recombination rate. Here, the latest research advances on CW pumped perovskite lasers are reviewed. First, the recent research advances on CW lasing in perovskite thin film are highlighted. Then, CW lasing in CsPbBr3 perovskite nanowires is briefly introduced. The comparison of lasing thresholds in CW perovskite lasers is made and discussed. Finally, the importance of such perovskite CW lasers is emphasized, while a perspective on the potential opportunities and remaining challenges of perovskite‐based CW lasers is proposed.
