Abstract
We succeeded in the experiments of the optical trapping and optical rotation of small particles by use of radiation pressure and the angular momentum of circularly polarized laser beam. The trapping was made two-dimensionally in the sample space of the optical microscope; The rotation of the sample was observed through the micloscope eye pieces. A heimispherical polystyrene latex of 7 μm diameter was rotated at the rate of 48 second per one turm by 514.5 nm wavelength 5 mW Argon-ion laser. Experimental apparatus and conditions are described and the results are analyzed, and discussed. The future applications of this technique are also discussed.
