Computational investigation of short pulse laser-induced modification of surface microstructure and photoacoustic control of surface diffusion

Abstract

Rapid progress in the development of accessible sources of short (pico-and femtosecond) laser pulses opens up new opportunities for surface modification with high accuracy and spatial resolution. In particular, the shallow depth of the heat-affected zone in short-pulse laser processing of strongly absorbing materials can result in the confinement of the laser-induced structural modifications within a surface layer as small as tens of nanometers. The small size of
