METHOD FOR PRODUCING A LIGHT DEFLECTION STRUCTURE, USE OF A SUBSTRATE WITH A LIGHT DEFLECTION STRUCTURE OF THIS TYPE, AND LIGHT DEFLECTION UNIT COMPRISING A LIGHT DEFLECTION STRUCTURE OF THIS TYPE

A method for producing a light deflection structure includes the steps of: a) producing a first plurality of interaction regions, in which at least one laser beam interacts with the substrate material along a first path with a spatial overlap of the interaction regions, b) producing a second plurality of interaction regions with a spatial overlap of the interaction regions along a second path offset with respect and with a spatial overlap with the first path, c) optionally producing a further plurality of interaction regions with a spatial overlap of the further interaction regions along a further path offset with respect to and with a spatial overlap with the path used immediately before, and d) optionally carrying out step c) multiple times. The method also includes producing type II modifications of the substrate material, and changing at least one process parameter from one beam path to another beam path.
