Problems solved by technology

[0004] However, the amplification of high-power disk lasers is restricted by the pumping method. Using the existing technology to realize the scaling of the output power of high-power disk lasers and obtain the power amplification of high-power disk lasers is limited by the processing size of the aspheric mirror and the adjustment accuracy. Restricted by technical factors such as

Abstract

The invention discloses a disc laser, which comprises eight parts: an LD pump source, a homogenizing rod, a focusing system, a focusing mirror, a reflector set, a disc crystal, a heat sink, an outputcoupling mirror and the like. A semiconductor laser is used to perform multiple times of end-surface pump on the disc laser; and through an inclined through hole on a belt at the front end of the focusing mirror, incident pump light is directly irradiated on the disc crystal and reflected by the reflector set, and multiple times of absorption of the pump light by the disc crystal can be realized.The rear surface of the disc crystal is coated with a laser high reflective film, a resonant cavity is formed with the output coupling mirror, and laser output is acquired.

Description

technical field [0001] The invention relates to the field of all solid-state lasers, in particular to the field of a disc laser. Background technique [0002] Disk laser is a new type of laser with high average power, high beam quality and high conversion efficiency. At present, a new generation of solid-state lasers represented by fiber lasers and disk lasers has become a typical representative of the laser family. Since the crystal of the disk laser is very thin, the absorption of the pump light is limited each time, so it is necessary to use a multi-stroke pumped disk laser to allow the pump light to pass through the disk laser multiple times to obtain high absorption of the pump light. Efficiency, so multi-stroke disk laser pumping, high-power disk solid-state laser high-efficiency and stable operation of the core technology. Among them, the amplification of the disk laser is mainly to increase the pumping area on the disk crystal. [0003] In 2003, U.S. Patent Steffe...
