Abstract

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 polystyrene particle placed into three interfering beams laying in one plane and creating two dimensional optical lattice. Colloids behavior in this type of optical landscape differs according to the colloid size. Spatial distribution of the optical force and torque is studied and particle behavior is predicted. Total optical force and torque are presented for various optical lattice configurations.
