METHOD FOR REDUCING CUTTING CONICITY AND INCREASING CUTTING SPEED USING MULTIPLE ULTRAFAST LASER BEAMS

WIPO Patent Application WO/2019/019424

A1

A method for reducing cutting conicity and increasing a cutting speed using multiple ultrafast laser beams during laser cutting, comprising the following steps: dividing one laser beam into at least two laser beams; and focusing the at least two divided laser beams onto a surface of a sample through a focusing lens to form multiple arranged focal points. According to the method, the concentrated energy characteristic of a small light spot is utilized to reduce the conicity, and the mutual effect between the focused laser beams and a material further enhances the energy utilization efficiency.
