Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings and embodiments, but the protection scope of the present invention should not be limited thereby.

[0019] Referring to the accompanying drawings, Fig. 1 is a top view of a preferred embodiment of the laser of the present invention; Fig. 2 is a cross-sectional view of A-A' of Fig. 1 . As can be seen from the figure, the composition of the annular mixing cavity solid slab laser with reverse wave suppression in the present invention is: with the optical axis of the laser as the center line, a triangular prism 2, a slab gain medium 1, a scraper mirror 3, and a beam expander are placed in sequence. System 4, the first total reflection cavity mirror 5, the scraper mirror 3, the first total reflection cavity mirror 5 and the second total reflection cavity mirror 6 are all placed at a certain angle with the optical axis, so that through the scraper mirror 3 , the second total re...

Abstract

Provided is a solid-state slab laser with reverse phase wave restrain annular mixed cavity, which is comprised by disposing a triangular prism, a slab plus medium, a scraper mirror, a beam expander system, a first total reflection cavity mirror on light axis in sequence. The scraper mirror, the first total reflection cavity mirror and a second total reflection cavity mirror are all disposed in a certain angle to the light axis, so that the beam refracted and reflected by the scraper mirror, the second total reflection cavity mirror and the first total reflection cavity mirror and the beam expender system is reflected out by the scraper mirror. Shape regulation coupling system and semiconductor laser diode array are symmetrically arranged in sequence from inside to outside in width direction of the slab plus medium which serves as center. The upper and lower large surface of the slab plus medium, in thickness direction, respectively cling to a first micorchannel radiator and a second one. The invention has compact structure, so that stable laser output of high repetition frequency, high efficiency, high beam quality can be obtained.

Description

technical field [0001] The invention relates to an all-solid-state laser, in particular to a solid-state slab laser with backward-wave suppressing annular mixing cavity. Background technique [0002] At present, the well-known high-power slab laser resonator is a standing wave cavity, which is a round-trip loop composed of two or more mirrors. When the pump light enters the gain medium, it forms a coherent oscillation under the constraints of the mirror, so that in the oscillation Laser light is formed in the direction. However, the standing wave cavity cannot fully extract the pump energy, and the cavity itself cannot eliminate the uneven distribution of the gain, thereby reducing the utilization of pump light and reducing the energy of the final laser output. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiency of the existing high-power slab laser resonator, and provide a ring-shaped mixing cavity solid slab laser with b...
