Abstract |
This paper analytically investigates the pico second-pulsed laser processing of PMMA. Short-pulsed laser processing is a well-established tool for polymer. However the ablation mechanism of laser processing for polymer has not been thoroughly understood yet. This study utilized a thermal transport model to analyze the relationship between the ablation rate and laser fluence. This model considered the energy balance at the decomposition interface. The calculated variation of the ablation rate with the logarithm of the laser fluence agrees with the measured data. It is also validated in this work that the variat ion of the ablation rate with the logarithm of the laser fluence obeys Beer’s law. Keywords - Short-pulse laser, Microscale, Ablation | |||||||||
