  • Publication number: 20250108461
    Abstract: The present invention discloses a multi-dimensional laser scanning processing device and method, which includes a horizontally arranged laser beam, a turning optical path module arranged at one end of the laser beam along a horizontal direction. The turning optical path module is used to deflect the laser beam by 90°, which is then arranged to enter a deflection module. The deflection module is used to deflect the laser beam by 90° again so that it enters the beam expansion module along the horizontal direction. The beam expansion module 4 is arranged to expand a beam radius of the laser beam to a certain multiple, which then enters the plane scanning module, and finally enters the focusing module to converge into an ideal spot. The present invention can realize the changes of focused laser beam in the XYZ space and the two inclination angles ? and ? of the optical axis.
