Non-thermal ablation of expanded polytetrafluoroethylene with an intense femtosecond-pulse laser.
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 (-CF(2)-...

متن کاملStudies of the plume emission during the femtosecond and nanosecond ablation of graphite in nitrogen
Comparative studies of the pulsed laser ablation of graphite in 20 mTorr of N2 using both 15 ns and 450 fs pulses at a wavelength of 248 nm are reported. Emissions from the resulting ablation plumes, and from collisions with ablated material and the background N2 gas molecules, have been investigated by wavelength-, space-, and time-resolved optical emission spectroscopy OES , and the observati...
متن کاملFemtosecond laser induced surface nanostructures on copper
This study demonstrated circular surface nanostructures and femtosecond laser-induced periodic surface structures (FLIPSS) for copper produced by a Ti:Sapphire femtosecond laser beam of wavelength 800 nm and duration 120 fs. The circular textured nanostrucres could be created by a single laser pulse. The nanostructures in the center of the heated spot diminish as laser fluence increases and a c...
