Optical guiding of absorbing nanoclusters in air

Shvedov, Vladlen; Desyatnikov, Anton S; Rode, Andrei V; Krolikowski, Wieslaw; Kivshar, Yuri


We suggest a novel approach in all-optical trapping employing a photophoretic force for manipulation of absorbing particles in open air. We demonstrate experimentally the robust three-dimensional guiding, over the distances of a few millimeters, of agglomerates of carbon nanoparticles with the size spanned from 100 nm to 10μm, as well as their acceleration up to velocities of 1 cm/sec. We achieve stable positioning and guiding of particles as well as simultaneous trapping of a large...[Show more]
