Abstract

We demonstrate that a speckle pattern in the spatially coherent laser field transmitted by a diffuser forms a multitude of three-dimensional bottle-shaped micro-traps. These multiple traps serve as a means for an effective trapping of large number of air-born absorbing particles. Confinement of up to a few thousand particles in air with a single beam has been achieved. Theoretical analysis of the speckle defined trapping volume and the trapping light power is in a good agreement with experimental results on capturing of aggregates of carbon nanoparticles in air.
