Laser Heating of Solids
We are concerned with heating metals and semiconductors to produce a change in their properties in the heated region only. The change may be a solid to solid conversion as in heat treating steels, a solid to liquid to solid conversion as in semiconductor annealing or a solid-to-liquid-to vapor conversion as in cutting or drilling. The questions which we might wish to answer before designing a processing procedure include
What sort of laser do we need?
How must it be delivered to the sample?
How long should it dwell on the irradiated site? and
Will there be any unwanted side effects?
