Paper Abstract

The real time control of the rotation rate of a microscopic particle trapped in a focused laser beam by mean of polarization ellipticity of laser radiation has been studied. The ellipticity change was carried out with the modulator using orientational S-effect in nematic liquid crystals. The dependence of the particle rotation speed on the state of polarization ellipticity was determined. The calculation of an angular momentum of rotation per a unit of energy of the light field is shown.
