Abstract

There is proposed and described a physical model for possible sequence of effects induced by femtosecond high-intensity laser pulses in semiconductor and dielectric crystals. Basic points of the model are considered on the basis of the simplest estimations allowing to judge if the points do not contradict general physical regulations. Main advantage of the proposed model is capability of explaining extremely deep heating induced by super-short laser pulses and drilling of high-aspect holes.
