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 SnF 2 treatment, these lead‐free “green” perovskites yield stable coherent light emission extending to ≈1 μm at strikingly low thresholds.
