ABSTRACT

Ultrashort-pulsed lasers have been attracting worldwide interest in science and engineering. Studying the thermal deformation induced by ultrashort-pulsed lasers is important for preventing thermal damage. This article presents a new numerical method for studying thermal deformation in 3D double-layered film micro-structures exposed to ultrashort- pulsed lasers. The method is demonstrated by investigating thermal deformations in a 3D double-layered thin film and a 3D double-layered sphere, respectively.
