Abstract
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 9 Elsevier Science B.V. All rights reserved.
