Abstract

The twisted hollow beam was generated by transformation of Hermite-Gaussian beams through an optical system, consisting of three rotated cylindrical lenses. The intensity distribution and phase structure of the twisted hollow beam were theoretically analyzed by using Collins diffraction integral. In the experiment the twisted hollow beam was generated by transforming the Hermite-Gaussian mode TEM_m,0 of a diode pumped Nd: YAG laser. Micro particles were trapped by this hollow beam and rotated due to the twist (angular momentum).
