ICALEO 2000: Proceedings of the Laser Materials Processing Conference, 2000
A new type of laser processing called “laser shock cleaning” in which the removal of the small particles is carried out by shock waves produced by laser sparking in air, is reported. The removal of very small metal particles (less than 1 μm in diameter) from silicon wafer surfaces was demonstrated successfully by this new technique.

Laser cleaning was successfully applied to laser lap welding of SUS310S stainless steel and 6061 aluminum alloy. The length and width of the fish scale pit tended to increase and decrease with increasing the scanning speed from 3000 mm/s to 7000 mm/s ...

Detritiation of JET Tiles by Laser Cleaning
Fusion Science and Technology, 2008The retention of tritium (T) by carbon based deposits on tokamak surfaces is of increasing concern to the fusion community as the scale of tritium retention by this mechanism could be a limiting factor for the operation of fusion reactors, such as ITER.
