Behavior of colloidal microparticles in interference field created by several laser beams

摘要

In this paper we describe properties of optical forces and torques acting on colloidal particles placed into interference laser field created by three plane waves having wavevectors in one plane. We assume interference of all three beams and we study the properties of this 2D optical lattice and particle behavior. This set-up enables selective confinement according to particle sizes which could be used for optical extraction of some components from colloidal system.
