OPTICAL CAVITY FOR LASERS

摘要

IMPROVED LASER An improved laser particularly well adapted to produce high flux densities is disclosed. The disclosed laser includes an optical cavity wherein a curved window and a convex mirror make up one end wall assembly, such window and mirror being disposed with respect to each other in such a manner that the flux density at the window is less than the flux density at the mirror and, at the same time, energy reflected from the window constructively interferes with energy within the optical cavity.
