LASER PROCESS DEVELOPMENT
Name Description
Etching Delicate removal of material from the irradiated site at low energy densities.
Scribing Removal of material from the irradiated site using high energy densities, penetrating only partially through the thickness, resulting in a trough as the beam is scanned.
Cutting Removal of material from the irradiated site using high energy densities, penetrating completely through the thickness resulting in a cut; separating two pieces as the beam is scanned.
Drilling Removal of material from the irradiated site using high energy densities, penetrating completely through the thickness resulting in a "hole" as the beam is held stationary.
Stripping Removal of material from the irradiated site (usually a 3 dimensional surface) using medium energy densities, leaving the underlying material free from any damage.
Annealing Heat treating the irradiated area to the end result of permanently altering physical properties of the surface.
Marking Bleaching the irradiated area resulting in a color difference from the unexposed area. Physical properties of material are not changed when using low energy densities.
