Abstract
The use of solid-state lasers for the safe removal of contaminated and/or coated surfaces, in preparation for recoating or adhesion, is now an accepted industrial practice. By utilizing the flexibility of a nanosecond pulsed fiber laser of wavelength 1064 nm and varying laser fluence, pulse repetition rate, and pulse overlapping, an infinite array of substrate structuring can be achieved. The results are clearly shown in the images provided by the use of a Scanning Electron Microscope (SEM), demonstrating the various attainable substrate profile finishes and clearly indicating the almost infinite use of a solid-state laser for this purpose.
