Abrégé : front page image
(EN) The invention relates to a method for producing modifications (14) in or on a transparent workpiece (2) by means of a laser processing device (1), wherein a laser processing device (1) is used which has a short pulse or ultrashort pulse laser (10) that emits laser radiation (12) having a wavelength in the transparency range of the workpiece (2) and which has a beam-shaping optical unit (11) for beam shaping, in particular for focusing the laser radiation, and wherein a transparent workpiece (2) is used which is composed of a material that has a plurality of phases, of which at least two phaseshave different dielectric constants, of which in turn the one phase is a phase embedded in the form of particles, which phase is substantially surrounded by the other phase, and wherein the product of the volume of the particles specified in cubic nanometers and the ratio of the magnitude of the difference of the two different dielectric constants to the dielectric constant of the surrounding phase is greater than 500, preferably greater than 1000, especially preferably greater than 2000, such that the modifications (14) in or on the transparent workpiece (2) achieve a greater extent than ona workpiece composed of the same material that does not have a phase embedded in the form of particles.
(ZH) 本发明涉及借助于激光加工装置(1)在透明工件(2)之中或之上产生修改(14)的方法,其中使用激光加工装置(1),激光加工装置(1)具有发射在工件(2)透明范围内的波长的激光辐射(12)的短脉冲或超短脉冲激光器(10),并且具有用于光束成形、尤其是用于聚焦所述激光辐射的光束成形光学单元(11),并且其中使用由具有多个相的材料构成的透明工件(2),其中至少两个相具有不同的介电常数,进而其中一个相是以颗粒形式被包围的相,该相基本上被另一相包围,并且其中以立方纳米为单位表示的所述颗粒的体积和两个不同介电常数之差的绝对值与所述包围相的介电常数之比的乘积大于500,优选大于1000,更优选大于2000,使得相比于在由不具有以颗粒形式被包围的相的相同材料构成的工件上,在透明工件(2)之中或之上的修改(14)实现的程度更高。
