## Rotation of particles by using the beamwith orbital angular momentum

Gao Ming-Wei, Gao Chun-Qing, He Xiao-Yan, Li Jia-Ze, Wei Guang-Hui
• #### Abstract

The twisted stigmatic beam with an orbital angular momentum was generated by transforming the Hermitian-Gaussian beam of a laser-diode-pumped solid-state laser through a rotated cylindrical lens system. By utilizing the orbital angular momentum of the generated beam, an “optical spanner” was designed and developed. By using the optical spanner micro-sized particles were trapped and rotated.
