Abstract

The invention provides a laser power regulation device, a laser cutting device and a laser cutting machine. The laser power regulation device comprises a support, a laser device, a half-wave plate anda polarization beam splitting prism. The laser device is used for emitting cutting laser. The half-wave plate is rotatably arranged on the support. The light incident position of the half-wave platecorresponds to a laser head of the laser device. The light incident position of the polarization beam splitting prism is opposite to the light emergent position of the half-wave plate. The cutting laser emitted by the laser device passes through the half-wave plate and then passes through the polarization beam splitting prism. The polarization beam splitting prism is used for perpendicularly splitting P-direction polarized laser and S-direction polarized laser in the cutting laser. Through the laser power regulation device, the technical problem of how to stably and accurately regulate the output power of laser without affecting the output characteristics of the laser is solved.

Description

technical field [0001] The present application relates to the technical field of laser cutting, in particular to a laser power adjustment device, a laser cutting device and a laser cutting machine tool. Background technique [0002] With the rapid development of smartphones and the semiconductor industry, laser processing technology has become the main technology in the field of precision microfabrication. [0003] For the processing of different materials, the power of the laser needs to be adjusted. The traditional laser power adjustment is realized by adjusting the pump current inside the laser. Because the crystal inside the laser will produce a thermal lens effect when it is irradiated by the laser at high temperature, causing the crystal surface The occurrence of thermal deformation causes the laser to refract to different degrees, and the change directly changes the power of the laser. The change of the laser temperature will cause the thermal deformation of the cryst...
