We demonstrate a simple and high-performance laser-assisted technique for silver nanoring fabrication,
which includes the ablation of the Ag film by focused nanosecond pulses and subsequent reactive ion
polishing. The nanoring diameter and thickness can be controlled by optimizing both the pulse energy
and the metal film thickness at laser ablation step, while the subsequent reactive ion polishing provides
the ability to fabricate the nanoring with desirable height. Scattering patterns of s-polarized collimated
laser beam obliquely illuminating the nanoring demonstrate the focal spot inside the nanoring shifted
from its center at a distance of 0.57Rring. Five-fold enhancement of the photoluminescence signal from
the Rhodamine 6G organic dye near the Ag nanoring was demonstrated. This enhancement was attributed
to the increase of the electromagnetic field amplitude near the nanoring surface arising from
excitation of the multipole plasmon modes traveling along the nanoring. This assumption was confirmed
by dark-field back-scattering spectrum of the nanoring measured under white-light illumination, as well
as by supporting finite-difference time-domain simulations.
