Abstract

The invention provides a hybrid device and a laser, mainly relates to the technical field of laser, and can solve the problems of numerous optical components, large occupied space and relatively high cost in the existing laser. The hybrid device comprises an input end collimator, an output end collimator, a pump light collimator, an isolator, a filter and a beam combining module. The input end collimator is used for receiving signal light, the isolator is used for transmitting the signal light from the direction of the input end collimator to the filter, the filter is used for filtering the signal light to obtain first light, the pump light collimator is used for receiving pump light, and the pump light collimator is used for receiving second light. The beam combining module is used for carrying out beam combining processing on the first light and the pump light output by the pump light collimator to obtain first combined beam light, and the output end collimator is used for outputting the first combined beam light.

Description

technical field [0001] The present invention relates to the field of laser technology, in particular to a hybrid device and a laser. Background technique [0002] With the booming development of lasers, cost reduction has become a must for every laser manufacturer. Conventional high-power fiber lasers usually include multiple functional devices, and each functional device includes multiple components, such as an input collimator, an output collimator, and at least one corresponding functional component. In this way, the existing lasers have the problems of numerous components, large space occupation, and high cost, and since the functional devices and the functional devices need to be welded together by a welding machine, there will be a welding point, and each welding point will introduce a certain amount of energy. Splice loss and beam quality degradation affect the final beam quality of the laser. SUMMARY OF THE INVENTION [0003] In order to solve the above problems,...
