Modeling energy transfer in femtosecond pulsed laser ablation using coupled oscillators
We simulated the energy transfer in pulsed laser ablation (PLA) of copper using a coupled oscillator model. The data was taken from several literature about thermal energy transfer on PLA and applied to coupled oscillators. Two cases (position dependent and independent parameters) were tested and the observed results exhibit behavior similar to the two-temperature model. Additionally, maximum positions of the oscillator were compared to the threshold fluence of related studies and show striking similarities. With the given results, the coupled oscillator model presents capability in representing the thermal energy transfer in femtosecond pulsed laser ablation.
