Abstract

This study analytically investigates the picosecond laser ablation of poly(methyl methacrylate) (PMMA) and acrylonitrile butadiene styrene (ABS)/polyvinyl chloride (PVC). Pulsed laser ablation is a well-established tool for polymers. However the ablation mechanism used in laser processing of polymers is not thoroughly understood. This study utilizes a thermal transport model to analyze the relationship between the ablation rate and laser fluence. This model considers 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. This study also validates that the variation of the ablation rate with the logarithm of the laser fluence obeys Beer's law.
