Abstract

The application provides a cutting method for laser cutting glass, comprising: a laser cutting device with preset cutting parameters; the laser cutting device generates a laser beam according to the preset cutting parameters, and the focus of the laser beam acts on the glass to be cut. Under the action of the glass to be cut, a modified area is formed. Along the thickness direction of the glass to be cut, the width of the modified area becomes narrower from one side of the glass to be cut to the other; . The present application sharply increases the stress difference generated along the thickness direction of the glass to be cut, so as to realize rapid splitting of the glass to be cut.

Description

technical field [0001] The present application belongs to the technical field of laser processing, and in particular relates to a cutting method of laser cutting glass. Background technique [0002] In the prior art, laser cutting of glass generally adopts laser stealth cutting technology or Bezier cutting technology. Laser stealth cutting technology is to make a single pulse of pulsed laser through optical shaping, let it focus inside the glass material through the surface of the glass material, and the energy density in the focal area is high, forming a multi-photon absorption nonlinear absorption effect, so that the material is modified Cracks are formed, and then completely separated by mechanical means. Due to the insufficient depth of focus, laser stealth cutting technology is only suitable for thin glass; Bessel cutting technology uses the long-focus Bessel beam formed by the Bessel cutting head to focus on the In the vitreous body, it has a good effect when cutting ...
