Patent ID: 7068700

Claim:
A rugged resonator for a laser, the resonator comprising: a laser pump housing assembly, the laser pump housing assembly including: a laser pump housing; and a laser gain medium suitably mounted into or on the laser pump housing, the laser gain medium having a first and a second end; a resonator assembly, the resonator assembly configured to receive and hold the laser pump housing, the resonator including: at least four mirrors, a first, a second, a third, and a fourth mirror, the first mirror being configured to receive a first incident laser beam from the first end and to reflect a first reflected beam to strike the third mirror, the second mirror configured to receive a second incident laser beam from the second end and to reflect a second reflected beam to pass in proximity to the first reflected beam and to strike the fourth mirror; and an intra-cavity optics plate assembly, the plate including: an intra-cavity optics plate; an output coupler, affixed to the optics plate and configured to receive a laser beam reflected by the fourth mirror; and a high reflector, affixed to the optics plate and configured to receive a laser beam reflected by the third mirror.
