Abstract. Time-resolved studies on the ablation of metals (Ni, Ag, Au, Cu) and semiconductors (Ge, Si) by short UV laser pulses (500 fs at 248 nm) are presented. Submicron-period grating structures were created on the sample surface by UV pump pulses and the diffracted signals (0th, 1st, 2nd order) of a weak probe pulse (500 fs at 496 nm) were recorded as a function of pump-probe delay. These signals provide direct information about electronic excitations, phase transitions and the onset of material removal.
