Abstract

The invention discloses an optical path switching device and switching method for an optical shutter of a high-power optical fiber laser. The device comprises a stepping motor, a stepping motor fixingblock, a base plate, a reflector holder, a reflector, a limiting rod, an electromagnet and an electromagnet fixing block, which are combined into a whole and installed in the optical shutter. The reflector is installed on the reflector holder, and the stepping motor rotates the reflector holder to complete the switching of an optical path. The limiting rod limits the rotation position of the reflector holder; a strong magnet is installed on the reflector holder to be combined with the electromagnet; via power on and off of the electromagnet, the position of the reflector holder can be fixed,and the repeated positioning accuracy of the same can be improved. According to the optical path switching device and switching method, the switching of the optical path of the optical shutter can bemore reliable, and the stability of the optical shutter of the high-power optical fiber laser can be improved.

Description

technical field [0001] The invention belongs to the field of devices for optical fiber lasers, and in particular relates to an optical path switching device and a switching method for optical gates for high-power optical fiber lasers. Background technique [0002] High-power fiber lasers are widely used in cutting, welding, and material processing. The application of optical shutters for high-power fiber lasers enables one laser to perform multiple operations at the same time. Through the optical path switching of the optical gate, a laser system can provide multiple output terminals, which can be connected to different working units, and one laser can become the power source of multiple working units, which significantly reduces the user's investment in equipment. When the optical fiber at the output end of the optical gate is damaged or the use requirement changes, the optical fiber can be replaced at any time, which improves the simplicity of operation. With the developm...
