Abstract:
Scientists at Los Alamos have constructed a novel device for "seeing" tiny metal nanoscale particles by combining sub-wavelength, near-field imaging with broadband interference spectroscopy that uses the high-intensity illumination produced by an ultrafast laser - a laser that emits pulse durations lasting only of a few quadrillionths of a second. The technique could help scientists around the world gain a deeper understanding of the largely unseen nanoscale world.
