Preliminary studies of material surface cleaning with a multi-pulse passively Q-switched Nd:YAG laser

A multi-pulse Q-switched (MPQ) Nd:YAG laser system for surface material cleaning has been developed. Trains of pulses having total output energy of as much as 1.05 J , 10–30 pulses/train, 20– 70 ns individual pulse-width, and about 100 μs whole duration were generated. Ablation threshold fluence and...

Zusammenfassung:	A multi-pulse Q-switched (MPQ) Nd:YAG laser system for surface material cleaning has been developed. Trains of pulses having total output energy of as much as 1.05 J , 10–30 pulses/train, 20– 70 ns individual pulse-width, and about 100 μs whole duration were generated. Ablation threshold fluence and ablation rate for limestone substrate have been measured and compared with the theoretical calculations. Safe surface cleaning of limestone samples was demonstrated thanks to the high gap between the ablation threshold fluence of the substrate and black crust. Tests of surface cleaning for samples of stone, ceramics, and metal were performed.
