The effects of energy and pulse duration in laser ablation experiments have been investigated in the case of copper based alloys. Experiments were carried out near 530 nm by using two laser sources with different widths (8 ns and 250 fs). The craters generated by lasers were examined and their characteristics were related to different mechanisms involved in the ablation by laser pulses acting on different timescales. The optical emission of plasma produced was analyzed by LIPS, acquiring time resolved line intensities of the major elements contained in the samples, and determining plasma characteristics (temperature, electron density). Experiments demonstrated that fs and ns laser pulse must be modeled by different ablation regimes, the onset of which can be used to decrease the effect of fractionation on brasses and bronzes.
