Commercially available absorption filters were investigated with respect to their single- and multipulse ablation threshold using laser pulses from a Ti:sapphire laser in the range between 30 and 340 fs. It could be observed, that the threshold fluence decreases for shorter pulse durations. The similarity of the measured multipulse threshold fluences with those of undoped glass material suggests that, for very short pulses, the threshold is independent on the doping level and therefore, linear absorption does not significantly contribute to laser-induced damage.
