Gradient radiation forces exerted by strongly focused cylindrical
vector beams of radial and azimuthal polarizations on dielectric
spheres of different radii and refractive indices were calculated.
The effect of longitudinal and transversal components of the
focused electrical field on trapping properties was studied.
Experiments on optical trapping were performed using low-mode
optical fiber excited with Laguerre-Gaussian beam as a source of
the trapping beams.© (2004) COPYRIGHT SPIE--The International Society for Optical Engineering. Downloading of the abstract is permitted for personal use only.
