Abstract

The invention discloses a compact direct coupling all-solid-state laser device which mainly comprises laser diode pump sources, a laser crystal, a heat sink and a semiconductor cooler, wherein end faces and side faces of the laser crystal are plated with film. The laser crystal and the semiconductor cooler are fixed on two sides of the heat sink respectively. The laser diode pump sources are laser diode linear array double-side-face symmetrical pumps, and are arranged on two sides of the laser crystal respectively. A first laser crystal face is plated with laser all-trans film, and is a resonant cavity reflector, a six laser crystal face is plated with laser partial transmission film, and is a laser output mirror, a second laser crystal face and a fifth laser crystal face are semi-cylindrical lenses, and are plated with pump light total transmission and laser all-trans film, and texturing processing is carried out on a third laser crystal face and a fourth laser crystal face. According to the compact direct coupling all-solid-state laser device, a cavity-mirror-crystal integrated design is formed, adjustment of a cavity mirror does not need to be carried out, the compact direct coupling all-solid-state laser device is stabler, and integration of the compact direct coupling all-solid-state laser device is convenient.

Description

technical field [0001] The invention belongs to the technical field of all-solid-state lasers, and relates to a compact direct-coupled all-solid-state laser. Background technique [0002] All-solid-state lasers have the advantages of high conversion efficiency, good beam quality, long service life, and compact structure, and are a mainstream direction for the development of solid-state lasers. All-solid-state lasers are widely used in material processing, military applications and other fields. However, the current all-solid-state laser has limited integration, it is difficult to make the volume smaller, and the stability of the resonator is relatively poor, so the application is limited. [0003] Therefore, it is necessary to invent a new type of all-solid-state laser with a higher degree of integration and better stability of the resonator to meet the needs of a wider range of applications. Contents of the invention [0004] In order to overcome the defects and deficie...
