Dimensionless parameters for the design of optical traps and laser guidance systems

摘要: Optical traps are routinely used for the manipulation of neutral particles. However, optical trap design is limited by lack an accurate theory. The generalized Lorenz-Mie theory (GLMT) solves scattering problem arbitrary particle size and predicts radial forces accurately. Here we show that GLMT observed axial in a variety manipulators. We also present dimensionless parameter β prediction forces. Coupled with our correlation escape forces, now have set two simple correlations practical radiation-force-based systems.
