Embodiment Construction
[0044] Figure 1a A laser device 14, a solid body 2 irradiated with a laser beam 16 of the laser device 14 and an optical device 20 arranged between the laser device 14 and the solid body 2 are schematically shown in a possible arrangement in the device 1 according to the invention. The optical device 20 is preferably arranged and designed in such a way that a modification 18, in particular a lattice change, such as a crack or a local phase transformation, can be formed on the surface of the solid 2 or in the interior of the solid 2, ie with the solid 2. The surfaces are generated spaced apart. The modification is particularly preferably produced in the focal point of the laser radiation. The laser device 14 here emits laser radiation 16 with a preferred pulse duration in the range of preferably 100 fs to 1 ps and particularly preferably in the range of 5 fs and 10 ps. An application of the laser beam in the aforementioned range is advantageous since only a small or no therma...
