Abstract

The invention discloses a T-shaped switching device for a high-power optical fiber laser light path. The T-shaped switching device comprises an input optical fiber (1), an operation optical fiber (11), a main body seat (8), and a collimation assembly (2), a first coupling assembly (6) and a second coupling assembly (9) which are distributed in a T shape, wherein the input optical fiber (1) is inserted into the end part of the collimation assembly (2), a collimation lens group (21) is arranged in the collimation assembly (2), and a first focusing lens group (61) and a second focusing lens group(91) are respectively arranged in the first coupling assembly (6) and the second coupling assembly (9); a laser reflector (33) is arranged at the intersection point of the T-shaped distribution, thelaser reflector (33) is arranged at the end of the rotating mechanism, and the laser reflector (33) correspondingly rotates to a horizontal state and an inclined state forming an included angle of 45degrees with incident laser of the collimation assembly (2). The T-shaped switching device for the high-power optical fiber laser light path can simply and efficiently realize light splitting.

Description

technical field [0001] The invention belongs to the technical field of laser optical path switching, and more specifically relates to a T-shaped switching device for high-power fiber laser optical path. Background technique [0002] Conventional fiber lasers are equipped with an output fiber when they leave the factory. The optical fiber in the laser is integrally welded with the laser, and the core diameter of the output optical fiber cable is unique. It is designed for a single processing unit, and it is difficult to replace the output optical fiber when it is damaged. Based on the increasing demand for high-power fiber lasers in the application field, in order to improve the utilization rate of high-power fiber lasers, an optical path switching device that can easily switch channels is needed. By adding a splitting device to the high-power fiber laser, multiple fibers can be output at the same time, and different core diameters of each fiber can be used for different pro...
