Paper Abstract

We describe a general way how to calculate optical forces acting on Rayleigh particles or colloids placed into general interference field. In this paper we focus on a configuration with 3 beams laying in one plane and we present an analysis of the particles behaviour. We found that this arrangement can be used for sorting of particles having refractive index higher or lower comparing to the surrounding immersion medium and even for sorting of particles according to their size.
