ABSTRACT:
A solid-state laser resonator includes a pair of reflectors 4, 5, a bar-like laser medium 6, a plurality of point laser sources 1, 2 and resonator including a plurality of resonator portions. At least one of the paired reflectors 4, 5 has a curved-surface mirror. The laser medium 6 is interposed between the paired reflectors 4, 5. Laser beams 8 emitted from the point laser sources 1, 2 are passed through one of the paired reflectors 4, 5 and irradiated as pumping lights on one end face of the laser medium 6. The resonators include the pair of reflectors, the laser sources 1, 2 and a plurality of thermal lenses. The thermal lenses are formed within the laser medium 6. The resonators produce output laser beam to produce from the other end face of the laser medium 6 through other one of the reflector 5.
