Abstract

Ablation of expanded polytetrafluoroethylene without disruption of the fine porous structure is demonstrated using an intense femtosecond-pulse laser. As a result of laser-matter interactions near ablation threshold fluence, high-energy ions are emitted, which cannot be produced by thermal dissociation of the molecules. The ion energy is produced by Coulomb explosion of the elements of (-CF2-CF2-)n, and the energy spectra of the ions show contributions from the Coulomb explosions of the ions rather than those of thermal expansion to generate high-energy ions. The dependence of ion energy on the laser fluence of a 180-fs pulse, compared with that of a 400-ps pulse, also suggests that the high-energy ions are accelerated by Coulomb explosion.

SEM images: (a) cross-section of an ePTFE bulk sample; surfaces containing holes drilled by pulse irradiation of (b) 400 ps and (c) 130 fs. For pulses of 400 ps, fine structure is destroyed and aggregated ePTFE having a size of ~2 µm is produced. Holes for SEM imaging were produced by irradiation with 100 laser pulses having laser fluence of 8 J/cm2; produced holes were cut as shown in (d).
