Nanosecond pulses of Nd:YAG laser were used in all the cases at variation of the mode content of the laser beam which was achieved by applying a multimode fiber delivery of radiation. Both, air and water ambient were used in the experiments. The results are discussed in terms of plasma microexplosions in the domain of the substrate–layer interface and the vapor bubbles formation inside the thick rusty layer impregnated with liquid.
