Abstract

Scanning cw laser-induced temperature rise in anisotropic substrates has been investigated by simplifying and solving the dynamic heat equation in anisotropic media. It is found that the heat equation in anisotropic media can be simplified to a heat equation in isotropic media by coordinate transformation. The anisotropy of the media can then be reflected by heat source transformation. A general model was derived to calculate the scanning laser-induced temperature rise in anisotropic substrates. The result reveals that the substrate anisotropy affects both the peak temperature rise and the peak position.
