Laser cleaning of oxidized iron samples: The influence of wavelength and environment

A phenomenological laser-cleaning study of pure oxidized iron samples has been performed in order to model the influence of wavelength in air and the role of environment in the IR domain. Two sets of experiments were performed: (i) cleaning of oxidized specimens at different laser spot sizes and pulse numbers at wavelengths of 1064 nm and 532 nm in air and (ii) cleaning in air with electrolytes at 1064 nm for low energy densities.
