Paper Abstract

Optical guiding of micron-sized particles is shown using both Gaussian and zeroth-order Bessel light beams. Axial and transverse forces for guiding in both beams are calculated. Experiments show that the Bessel beam allows for extended guiding distances compared to a Gaussian beam, at the expense of guiding velocity.
