Abstract

The invention provides a multi-beam synthetic laser device capable of achieving flexible control. Through controlling n beam baffles to open or close by a controller, the number of reflected beams inputted to a beam combiner can be flexibly controlled, control of the output energy of the combined beams outputted by the beam combiner is finally achieved, and the defect that the working stability of a laser device is influenced by operating current increase or output power decrease of a laser device in the prior art is effectively solved.

Description

technical field [0001] The invention relates to the technical field of lasers, in particular to a flexibly controllable multi-beam synthesis laser device. Background technique [0002] At present, laser equipment that synthesizes multiple beams of laser light into one beam of laser light through a synthetic fiber and a beam combiner has been widely used, such as CN1896787A, CN108808441A. However, the existing multi-beam synthesis lasers simply combine fixed multi-beam lasers, and cannot flexibly control and select some of them for combination according to actual needs, which limits the scope of application of these devices to some extent. . [0003] The output power of the laser can be set and changed by adjusting parameters such as the working current of the laser. However, during the working process of the laser, if the power of the laser output by the laser is increased or decreased by changing the working current and other parameters, it will be due to the working param...
