Embodiment 1
[0042] The method is described in detail through Embodiment 1 in conjunction with the accompanying drawings.
[0043] Such as figure 1 Shown is a three-dimensional schematic diagram of an embodiment of large-format laser cutting of glass according to the present invention. The main equipment of the glass large-format laser cutting process is composed of a laser 1, a beam expander 2, a reflector 3, a digital galvanometer 4, a focusing field mirror 5 and a three-dimensional motion platform 6. The laser beam 7 emitted by the laser 1 passes through the beam expander 2 The beam expander and mirror 3 are reflected and transmitted into the digital vibrating mirror 4, and the digital vibrating mirror 4 scans the laser beam 7 along the set track under software control, and the scanning laser beam output by the digital vibrating mirror 4 is focused by the focusing field mirror 5 Form a focused spot with a peak power density higher than the damage threshold of the glass workpiece 8.
