Method of, and apparatus for, laser blackening of a surface, wherein the laser has a specific power density and/or a specific pulse duration

Research output: Patent

Abstract

A method of blackening a surface, comprises applying laser radiation to the surface of a target (10) to produce a periodic arrangement of structures on the surface of the target (10), wherein the laser radiation comprises pulsed laser radiation comprising a series of laser pulses and the power density of the pulses is in a range 2 GW/ cm² to 50 GW/cm² or 0.1 TW/cm² to 3 TW/cmz, and/or a pulse duration between 200 femtoseconds to 1000 picoseconds.
