Title:
METHOD FOR BREAKING AND CUTTING WITH LASER BEAM, METHOD FOR MANUFACTURING LENS OR LENS MOLD USING THE METHOD FOR BREAKING AND CUTTING AND LENS AND LENS MOLD FORMED WITH THE METHOD FOR MANUFACTURING
Document Type and Number:
Japanese Patent JP3886756
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a method for breaking and cutting with a laser beam, which is characterized by the fact that a thermal distribution is formed on the surface of a hard and brittle material and the hard and brittle material is stripped off due to the thermal distribution.
SOLUTION: The method is characterized by the fact that a laser beam absorption material is applied on the surface of the hard and brittle material, the irradiated laser beam is absorbed by the laser beam absorption material, the thermal distribution is formed on the surface of the hard and brittle material and the hard and brittle material is stripped off due to the thermal distribution.
