Laser optical shutter and laser

Abstract

The invention relates to the technical field of lasers, and discloses a laser optical shutter and a laser. The laser shutter comprises a laser input interface, a collimating lens, a plurality of laseroutput interfaces, a plurality of coupling lenses, and a plurality of light path switching assemblies, wherein each light path switching assembly comprises a rotary reflector and a fixed reflector, the plurality of rotary reflectors are installed on an incident light path of the laser input interface through corresponding first inclination angle adjusting mechanisms, and each fixed reflector is installed on an emergent light path of the laser output interface through a corresponding second inclination angle adjusting mechanism; a rotating shaft of the rotary reflector is connected to a rotarydriving mechanism, and the rotary driving mechanism is used for driving the rotary reflector to be switched between a light path connection position and a light path disconnection position. Accordingto the laser optical shutter, light path switching is achieved by rotating the rotary reflector, the stability is high, the switching speed is high, the inclination angle of the rotary reflector andthe inclination angle of the fixed reflector are independently adjusted, deflection adjustment does not need to be conducted on the coupling lens any more, and the adjustment difficulty is reduced.

Description

technical field [0001] The invention relates to the technical field of lasers, in particular to a laser shutter and a laser. Background technique [0002] High-power lasers of 6kW and above are more and more used in the automotive and new energy industries, and their production lines have extremely high requirements on the stability of the laser system. Especially in the power battery industry, aluminum and copper are the main welding materials for power batteries. Therefore, during laser processing, the laser is easily affected by high reflection, which leads to an increase in the failure rate of the laser system, which also restricts the stable production of the power battery production line. major hazards. [0003] The principle of the high-power optical gate currently used in the market is that the laser beam is collimated by the collimator, reflected by the mirror, and then directed to the focus lens, and then focused on one end of the transmission fiber by the focus l...
