摘要
This invention concerns a method of producing subsurface marking in a transparent body. According to the invention, the marking is done less than 500 μm below the surface by applying a layer system with a high destruction threshold, compared to the substrate, to the surface of the substrate. If the layer system is designed as an anti-reflection coating system for the reading wavelength, it increases the contrast for reading. If the layer system is designed as a mirror for the writing wavelength, the writing can be done in reflection at a lower intensity.
