摘要

The hyperbolic two-step model has attracted attention in thermal analysis of metal thin films exposed to ultrashort-pulsed lasers, because it is more suitable than the parabolic two-step model for the case when the laser pulse duration is shorter than the electron thermal relaxation time. In this article, we develop a hyperbolic two-step model numerical method for studying thermal deformation in a 3-D microsphere exposed to ultrashort-pulsed lasers. The method is illustrated by investigating thermal deformation in a gold microsphere. Results show that the change in electron temperature is very different in these two models.
