Optical micromanipulation using supercontinuum Laguerre-Gaussian and Gaussian beams

Opt Express. 2008 Jul 7;16(14):10117-29. doi: 10.1364/oe.16.010117.

Abstract

We characterize a single beam supercontinuum "white light" trap and determine the trap stiffness in the transverse trapping plane. We realize a holographic white light trapping system using a spatial light modulator, and explore the generation of a dual beam trap and characterize its performance. We also demonstrate optical trapping and rotation of particles using a supercontinuum vortex beam. It is shown that orbital angular momentum can be transferred to spheres trapped in a supercontinuum vortex. Quantified rotation rates are demonstrated.
