| 摘要 |
The invention relates to a method for producing a mark in a transparent body under the surface thereof. According to said invention, the mark is located at least at 500?m below the surface because a layer system, whose destruction threshold is greater than that of a substrate, is applied to a substrate surface. When the layer system is embodied in the form of a readout wavelength antireflection layer system, a contrast is increased during reading. The embodiment of the layer system in the form of a writing wavelength mirror makes it possible to write with reduced intensity reflection. |
