A numerical analysis of the conjugate optical-thermal fields in an amorphous silicon thin film deposited on a glass substrate and irradiated by a moving Gaussian laser source is carried out.

The combined optical and thermal models are solved by means of COMSOL Multiphysics.

Results are given for continuous and pulsed moving Gaussian heat sources and they are presented as temperature profiles and fields.
