Method for generating optically perceptible laser-induced cracks in brittle material |
摘要 |
The invention is directed to a method for generating optically perceptible laser-induced cracks in brittle material, wherein a laser beam, followed by a coolant jet, is guided relative to the surface of the brittle material in order to advance a crack trail into the material starting from an initial crack, and wherein a marking agent which penetrates into the crack during the formation of the crack so as to make the latter visible is mixed with the coolant.
