The present invention provides a wavelength locking system. The wavelength locking system includes: a spatial beam combining module, which includes a semiconductor light-emitting device; an external cavity mirror; and a first transmissive surface grating, which is located in the spatial beam combining module in the optical path between the external cavity mirror and the external cavity mirror; a second transmissive surface grating, the second transmissive surface grating is located in the optical path on the light-emitting side of the external cavity mirror, and the second transmissive surface grating is suitable for The dispersion of the light beam before the first transmissive surface grating to the external cavity mirror is compensated. The invention adopts the second transmissive surface grating to perform dispersion compensation on the light beam passing through the external cavity mirror, the quality of the output light beam is improved, and the output brightness is improved.
Description
technical field [0001] The invention relates to the technical field of semiconductors, in particular to a wavelength locking system. Background technique [0002] Semiconductor-pumped fiber lasers, solid-state lasers, and gas lasers have high output power and good beam quality, and have been widely used in industries, scientific research, and military that require high laser power output and high laser beam quality. Fiber lasers have strict requirements on the brightness of the pump source. At present, semiconductor fiber coupling modules are mainly used as the pump source. Solid-state lasers and gas lasers can be pumped using electrical, chemical, optical, and pneumatic pumping to achieve laser output. Compared with other pumping methods, the semiconductor laser diode optical pumping method has the advantages of high electro-optical conversion efficiency, compact structure, low cost and long life, and is currently widely used to pump solid-state lasers and gas lasers.
