In this book, we provided extensive discussions on key highlights in the Perovskite laser research field. In Chap. 1, we begin by briefly introducing the concept of stimulated emission, as it is key to the coherent properties of lasers. We have shown that minimally population inversion of carriers in three-level gain materials is a must for optical gain. Upon the inclusion of an external cavity, stringent boundary conditions impose further selection of allowed photon modes that can participate in laser mode oscillations.
