    A kinetic model of photoablation with the nanosecond pulses of an excimer laser, based on the so-called moving interface, is presented.

    Ablation rates in pulsed-laser processing depend heavily on the laser beam spot size. This has been observed for the first time for a number of different materials. Detailed investigations on this effect, performed by means of XeCl excimer-laser radiation and the example of LiNbO3, are reported...
