Novel single-mode high-power laser

Abstract

The invention discloses a novel single-mode high-power laser, and relates to the technical field of lasers. The novel single-mode high-power laser comprises a laser shell, and a light outgoing groove is formed in one side of the laser shell. According to the novel single-mode high-power laser, a hexagonal filter is arranged and is mounted in the inner cavity of a resonator, so that the novel single-mode high-power laser can have a relatively wide ridge width and can also achieve a transverse single-mode effect, the process is relatively simple, the cost can be reduced, the efficiency can be improved, the resistance of the device can be reduced due to a relatively large area, heat dissipation can be improved, and the maximum luminous power output can be increased.Compared with other traditional multi-mode high-power lasers, the novel single-mode high-power laser has the advantages of low optical coupling and loss when being in coupling transmission with optical fibers or waveguides, accordingly, the novel single-mode high-power laser is excellent in transmission light rate; and the laser is in transverse single-mode output, therefore, multi-mode optical fibers or waveguides with large pipe diameters can be used for transmission, the cost can be reduced, the transmission loss can be reduced, and the transmission power can be further improved.

Description

technical field [0001] The invention relates to the technical field of lasers, in particular to a novel single-mode high-power laser. Background technique [0002] Semiconductor lasers, also known as laser diodes, are lasers that use semiconductor materials as working substances; due to differences in material structure, the specific process of generating laser light for different types is quite special; commonly used working substances are gallium arsenide (GaAs), cadmium sulfide (CdS) , indium phosphide (InP), zinc sulfide (ZnS), etc. There are three types of excitation methods: electric injection, electron beam excitation and optical pumping; semiconductor laser devices can be divided into homojunction, single heterojunction, double heterojunction, etc.; homojunction lasers and single heterojunction lasers Most of them are pulsed devices at room temperature, while double heterojunction lasers can work continuously at room temperature. [0003] Existing lasers have a lar...
