摘要： In a symmetrically stable optical resonator, a first reference plane is set at an arbitrary position between the end face (102), opposing a partial reflector (2), and the neutral point (101) of a rod type solid state laser medium (1), and an aperture (5) having a diameter substantially equal to that of the rod type solid state laser medium (1) is arranged at a position optically symmetric to the reference plane with the partial reflector (2) as a neutral point using a relay lens (6) and a coupling lens (7) arranged between the aperture (5) and an optical fiber (8), the first reference plane is transfer-relayed onto the incident end face of the optical fiber (8), and the aperture (5) is transferred onto the coupling lens (7) through the relay lens (6). Even when the focal length of thermal lens of the rod type solid state laser medium (1) or pointing of laser light is varied, beam transmission is performed by an optical fiber excellent in stability and reliability and condensation of laser light exiting the optical fiber is sustained constantly.

摘要： In a rod-type solid laser apparatus, a laser rod 1 is held by a rod holder 5, the rod holder 5 is held in a recessed portion 40 formed in an adjust ring 7, and the adjust ring 7 is mounted on a cavity container 4. The rod holder 5 is pressed against the cavity container 4 by the bottom surface of the recessed portion 40 of the adjust ring 7, and the diameter of the recessed portion 40 is set slightly larger than the outside diameter of the rod holder 5, whereby the rod holder 5 can be moved freely in the radial direction of the recessed portion 40 within the recessed portion 40. On the adjust ring 7, there are radially disposed two adjust screws 8a, 8b and a spring 9 which respectively extend from the side surfaces of the adjust ring 7 into the recessed portion 40 in such a manner that they are contacted with the rod holder 5. The rod holder is pressed and supported by three points, that is, the respective leading ends of the adjust screws 8a, 8b and spring 9. In the above-structured rod-type solid laser apparatus, when the screwing amounts of the adjust screws 8a, 8b are adjusted, not only the spring 9 can be expanded and compressed but also the position of the rod holder 5 can be adjusted.
