摘要: The invention relates to a method for removing brittle-hard material by means of laser radiation, wherein removal depression forms in the as result removal, surfaces, also designated flanks, which have diffractive and refractive effect on radiation introduced and, result, portions said generate interference diffraction patterns within which, soon again impinge surfaces penetrate into volume, bring about there that is spatially variable along consequence roughen surface induce cracks volume. A wavelength mixture comprising at least two wavelengths used being chosen such are established account refraction both volume way spatial positions maxima one (or more) fall minima other wavelength(s).
