XeCl excimer laser ablation of a polyethersulfone film: Dependence of periodic microstructures on a polarized beam

Abstract
Highly periodic stable microstructures appeared on the surface of polyethersulfone (PES) by XeCl excimer laser ablation with a single polarized beam in ambient air. Its formation mechanism was investigated using the time-resolved light scattering technique with the pulsed light of an XeF excimer laser. In addition to the polarization of the ablating beam, thermal processes on the etched surface play a significant role in microstructure formation.
