In devices, in which a qusi-2D perovskite film with an optical resonator, we can clearly see lasing, with an FWHM value of < 1nm, under optical pumping. Additionally, we realize continuous-wave lasing from perovskites at room temperature in air. It is worth mentioning that continuous-wave laser intensity is very stable over 30 min. Perovskites are an excellent gain medium for future electrical lasing.
