Abstract
Transfer of orbital angular momentum to a low-index particle trapped in optical tweezers, was demonstrated. The particle was constrained to the dark regions between adjacent bright rings of a high-order Bessel beam. Particle rotation rates were consistent with a computer model, which considered scattering as the dominant mechanism for transfer of orbital angular momentum. Quantitative comparison between theory and experiment showed good agreement for rotation rates.
