Laser-induced surface damage: multi-photon absorption or avalanche breakdown

Not Accessible

Your library or personal account may give you access

Abstract

The interaction of intense pulsed laser radiation with solid surfaces is usually accompanied by macroscopic damage. In many cases, as for wide bandgap materials, the initial energy absorption mechanism leading to surface damage is still an open question. Possibilities are multiphoton absorption bridging the bandgap1 and avalanche breakdown.2
