[7p-S44-4] Orbital Rotation of a Trapped Particle Using a Focused, Circularly-Polarized Light

Keywords:optical trapping, orbital rotation

We have demonstrated orbital rotation of a trapped particle using a circularly-polarized light focused on a boundary of a glass substrate and solution. The trapped particle is polystyrene bead with a diameter of 600 nm and involves fluorescent molecules. A shift of the minimum potential position arises from nonlinear effect on the trapped particle with two-photon absorption. Thus, it is assumed that excitation orbital rotation is caused by generating nonlinear polarization on the particle and transferring angular momentum from photons to it.
