Paper Abstract

We have investigated laser-trapping of light-absorbing particles in air with a single laser beam. We have studied possibilities of using lenses with a long focal length for trapping light-absorbing microparticles with a spatial light modulator. Finally, we demonstrate photophoresis-based optical trapping of absorbing airborne nanoclusters with a lens with a long focal length. In these experiments, we used an optical setup with a spatial light modulator. In contrast to experiments with a short focal lens, we were able to manipulate a much smaller number of particles in these experiments. A mechanism for such optical trapping is discussed by considering the combined action of several forces affecting the trapped particles.
