    Abstract

    The impact of laser ablation of polytetrafluoroethylene (Teflon) in ambient air was discussed. The importance of Teflon in bioscience and medical applications was also discussed. The quality of the ablated structure was degraded and the ablation efficiency was reduced because of the air ionization effect at high laser fluences. Laser fluence was kept below a critical fluence to obtain high quality microstructures.
