    "abstract": "We derive a partial-wave (Mie) expansion of the axial force exerted on a\ntransparent sphere by a laser beam focused through a high numerical aperture\nobjective. The results hold throughout the range of interest for practical\napplications. The ray optics limit is shown to follow from the Mie expansion by\nsize averaging. Numerical plots show large deviations from ray optics near the\nfocal region and oscillatory behavior (explained in terms of a simple\ninterferometer picture) of the force as a function of the size parameter.\nAvailable experimental data favor the present model over previous ones.",
