Abstract

We studied experimentally and theoretically the formation of one-dimensional optically bound structures of polystyrene particles placed near the surface. These structures were created as the result of the illumination of a colloidal suspension by relatively wide Gaussian beam (beam waist 20 μm and wavelength 532 nm) that was reflected backwards with a tiny tilt with respect to the incident beam. We have measured quantitatively the binding forces between individual particles and compared the experimental results with the theoretical simulations based on the coupled dipole method (CDM).
