Abstract

The invention pertains to a method for lowering the ablation threshold of a laser-ablated material by having on a surface of the laser-ablated material a structuring which reduces the reflection of a laser beam. The ablation threshold can be further lowered by heating the material as well as by chemically modifying the material or its surface, even slightly. The invention facilitates industrial implementation of machining of a number of various surfaces and materials. The invention also pertains to target materials to be ablated.
