Abstract

Optical guiding of microscopic particles in femtosecond and continuous wave Bessel light beams is studied and compared. We confirm that optical guiding is an average power effect and observe no difference in the guiding velocities of non-fluorescing polymer spheres. Furthermore, we observe second harmonic generation of guided KTP crystallites in femtosecond Bessel light beams. This observation opens up the prospect of using multi-photon effects in optical manipulation for applications such as optical identification of guided cells for sorting purposes.
