The family of solution-processed tin-based perovskites is demonstrated as a new and superior near-infrared gain medium. Due to the large electron-hole bimolecular recombination associated with tin and the reduced trap density with SnF2 treatment, these lead-free "green" perovskites yield stable coherent light emission extending to approximate to 1 mu m at strikingly low thresholds.
