Laser ablation caused by geometrically constrained illumination and inventive target design
Abstract
Modern laser technologies use very sophisticated manipulations with (i) a photon cloud forming an irradiation beam and with (ii) disign of a target. E.g. high numerical aperture illumination at very small, diffraction limited conditions is employed for fabrication of the tiny solitary nanoformations on surface of specially prepared thin films deposited onto usually dielectric or semiconductor substrate. In the paper below we list such cases and consider an example with a free standing gold nanofilm modified by tightly focused femtosecond laser pulse.
