Abstract
Laser is a versatile source of energy that has been widely used in material processing such as cutting, drilling, welding and etching. It had been applied to most materials including metals, insulators, semiconductors, polymers and magnetic materials. Therefore, it is necessary to understand the surface absorption in the study of thermochemical, photochemical and thermal processing in laser microprocessing. Models of temperature distribution by irradiation of laser beam had been introduced by several groups such as Moody1 and Lax.2 In this study, the polarization dependence of surface absorption is incorporated into the laser-induced temperature model to investigate the polarization effect in laser processing.
