A. Semerok et al., Experimental investigations of laser ablation efficiency of pure metals with femto, pico and nanosecond pulses, APPL SURF S, 139, 1999, pp. 311-314
Laser ablation efficiency of metals in terms of ablated volume per unit of
energy was studied experimentally in air at atmospheric pressure with sharp
ly focused ns, ps and fs laser pulses. The best efficiency was obtained for
fs laser. Crater widening at ps and ns pulses and correlation between the
ablation efficiency and melting point temperature were observed. Ablation e
fficiency dependence of pulse duration and wavelength is discussed. (C) 199
