Polaritonic emission based on cooperative coupling of photons with excitons and/or phonons in molecular crystals is an intriguing way to realize organic lasers. As reviewed by Hisao Yanagi and co‐workers in article number 1900136, single microcrystals of thiophene/phenylene cooligomers exhibit exotic light amplification behaviors such as pulsed emission with unusual time delay and spectral splitting as well as enhanced off‐resonant Raman scattering unlike the stimulated emission process in conventional photon lasing.
