Author Affiliations +
We describe a general way how to calculate optical forces and torque acting on colloids placed into laser interference field. In this paper we focus on a configuration with three interfering beams laying in one plane and we present a comprehensive analysis of trap properties and particle behaviour. We found that this arrangement can be used for sorting of particles according to their size or refractive index.
