Abstract:

We study the maximum temperature rise induced by a rotating or dithering Gaussian laser beam on a two-layer body. First, we derive semi-analytical solutions by solving the transient three- dimensional heat equation in a semi-infinite domain with insulating surface. Second, we provide numerical solutions for a two-layer structure in a finite domain. Our results show that the maximum temperature rise can be reduced significantly either by applying a thin layer of coating on the protected object or by moving the beam or equivalently the object.
