[9p-Z17-20] Particle Size- and Refractive Index-Dependence of Optical Force at Wide-Area Micro Particle Array due to Focused Laser

Keywords:Optical Manipulation, Polystyrene Particle

We focus on a scattered light field from widly and optically trapped polystyrene nanoparticles by a single focused laser. At out of focused irradiation area, the optical trapping is significantly affected by the parameters of particles determing the sacttering field. In this talk, we discuss the dependence of optical trapping on the particle size and the refractive index. Then, we reveal a physics of the indirect optical trapping mechanism.
