Abstract Perovskite materials have emerged as promising candidates for various optoelectronic applications owing to their remarkable properties and easy solution processing. Metal halide perovskites, direct-bandgap semiconductors, show an excellent class of optical gain media, which makes them applicable the development low-threshold or even thresholdless lasers. This mini review explores recent advances in perovskite-based laser technology, led chiral single-mode microlasers, low-threshold, external-cavity-free lasing devices at room temperature, other innovative device architectures. Including self-assembled CsPbBr 3 microwires that enable edge lasing. Realized continuous-wave (CW) pumped by perovskite material pushes research electrically driven The capacity regulate charge transport perovskites further enhances applicability systems. ongoing integration with advanced photonic structures holds potential future innovations technology photovoltaics. We also highlight transformative advancing next generation efficient integrated devices.
