Optical rotation of small particles by a circlarly-polarized laser beam in an optical microscope.

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