Abstract. Standard anodized aluminium samples with about a 20-μm-thick oxide layer were investigated for cleaning study by means of laser pulses. The removal caused by overheated melting and mechanical stress was studied at wavelengths of 1064 nm and 532 nm. The samples were examined with scanning electron and optical microscopy. We investigated the dependence of the laser cleaning efficiency on energy densities and the number of pulses. The layer removal mechanisms were compared on natural and black anodized aluminium samples. Due to the different absorptiveness of both layers, the ablation threshold varies. Furthermore, the ablation mechanism investigated using microscopy and photoacoustic measurements, respectively, varies with the absorptivity.
