Description

technical field [0001] The invention belongs to the technical field of semiconductor optoelectronics, and more specifically relates to a microchannel semiconductor laser. Background technique [0002] With the continuous improvement of the performance of semiconductor laser chips and the continuous decline of production costs, high-power laser devices represented by wavelengths such as 8xx, 9xx, and 106x have become the core devices of laser processing systems and play an increasingly important role in the field of laser manufacturing. role. [0003] The laser is used in industrial processing, and it needs a certain amount of optical power to heat up and process. If the optical power is insufficient, the power density is not enough, and the processing effect cannot be achieved. At present, the optical fiber coupling output and the focusing lens are used for energy concentration to increase the power density, but the power is insufficient to achieve the processing effect. ...
