Abstract

Method involves using high power density beam (3) to introduce the engraving (2) that is focused in a working region immediately below the surface of the flat body (1). The beam is focused in a layer below the flat body surface that is about 25 per cent of the thickness of the flat body. Independent claims are also included for the following: an arrangement for introducing at least one internal engraving into a flat body.
