We have observed laser action in single‐crystal ribbon whiskers of GaAs. The whiskers were grown with various dopants by a vapor transport process and were used, as grown, in an ultrashort cavity composed of high reflectivity dielectric mirrors. The structure was longitudinally photopumped, and it operated in a single mode at room temperature.
