Problems solved by technology

[0003] At present, the diode laser pump heads with less than 100 watts are more common in the market. For solid-state lasers with hundreds of watts, the lamp pumping method is basically adopted, and there are no domestic reports on diode-pumped solid-state lasers with kilowatts. , kilowatt-class laser systems used in industry also mainly rely on CO 2 laser

Abstract

The invention relates to the technical field of photoelectron, and discloses a diode laser pump head, which comprises a polygonal closed-type pump cavity, a laser crystal, two end plates, two support plates and a bottom plate, wherein the polygonal closed-type pump cavity is used for irradiating light emitted by a array device of a semiconductor laser on the laser crystal in the pump form of ambient light; the laser crystal is positioned inside the polygonal closed-type pump cavity; the two end plates are used for refrigerating the diode laser pump head and hollowing the center thereof, and fixed at both ends of the polygonal closed-type pump cavity; the two support plates are used for fixing the polygonal closed-type pump cavity and the laser crystal, and fixed between the polygonal closed-type pump cavity and the two end plates; and the bottom plate is used for refrigerating the diode laser pump head, provided with at least a water inlet and at least a water outlet, and fixedly connected with the two end plates. The invention provides the diode laser pump head of a hundreds watt and kilowatt class with continuous power output, and can be applied to a DPSSL system.

Description

technical field [0001] The present invention relates to the field of optoelectronic technology, in particular to a diode laser pump head, which is an optoelectronic device composed of a high-power diode array laser and a laser crystal, that is, a diode-pumped solid-state laser (DPSSL for short) is a key device in solid-state lasers with hundreds of watts and kilowatts of continuous power output. Background technique [0002] Diode-pumped solid-state lasers are an important part of the laser family. It combines the advantages of diode lasers, such as high efficiency, small size, and light weight, and the advantages of solid-state lasers, such as good beam quality. and other fields have broad application prospects. The components of diode-pumped solid-state lasers can be mainly divided into: diode pump source, laser crystal, resonator, power supply equipment, and refrigeration equipment. Among them, the combination of diode pump source and laser crystal is also called "diode ...
