Conference on Lasers and Electro-Optics (CLEO), San-Jose, Costa Rica, 8 - 13 June 2014
We report nanometer-size patterning of various thin films by femtosecond pulsed Bessel beams. Nanoslit arrays fabricated on gold films exhibit excitation of surface plasmon polaritons. We extend the approach to single-atomic-layer systems such as graphene.
