Laser is a flexible tool for processing thin solid films in industrial context. However, further understanding of the interaction is necessary to gain better control and precision. In this context, developing a predictive numerical model is of high interest.

 

In this work, we show the results of numerical simulations of the irradiation of a thin molybdenum film deposited on a glass substrate by a single laser pulse. The laser pulse duration and wavelength are 200 fs FWHM and 400 nm, respectively. The model is based on a two-temperature model and accounts for the possible melting of the material. Validity of the numerical scheme is ensured by tracking the conservation of energy. The calculated melting thresholds of the film shows an excellent agreement with existing experimental data for a number of molybdenum film thicknesses.
