Summary form only given. A method of producing single-mode output from multimode optical fibers is described. A multimode optical fiber is placed within a laser resonator. The latter is configured so that at the output of the fiber an ordinary dielectric mirror that selectively reflects only the lowest order mode back into the fiber forms one of the resonator end mirrors. At the other end of the fiber a phase conjugate mirror reflects the multimode pattern generated from the reflected single mode light. The phase conjugate mirror thus launches a reflection that perfectly unscrambles the mode conversion on the return pass, preserving the single-mode radiation pattern at the output. The operation of a resonator of this type using a crystal of barium titanate pumped by a single-mode (longitudinal and transverse) argon-ion laser as the phase conjugate reflector is described.
