Interaction of short and intense laser pulses with dielectric materials: from absorption to ablation
Université de Bordeaux-CNRS-CEA, Centre Lasers Intenses et Applications, UMR 5107, 351 Cours de la Libération, 33405, Talence, France
Modeling of the interaction of short laser pulses with dielectric materials is addressed. Based on phenomenological considerations, it is shown how the transition from primary absorption to ablation takes place. This description is illustrated by two particular examples allowing to highlight specific physical phenomena. An accurate estimate of the early absorption, which strongly depends on material characteristics, is shown to play an important role. An approach to evaluate this early absorption is presented.
