Abstract

We used a spring-mass coupled oscillator model to simulate thermal energy transfer during femtosecond pulsed laser ablation (fs PLA) of two-layer metal (gold and silver) described by two-temperature model. The data for thermal energy transfer from various literature sources on fs PLA was incorporated into the coupled spring-mass oscillator model. Two cases (position independent and position dependent parameters) were conducted and the observed results in both cases demonstrated behavior similar to the two-temperature model.
