Optical Torque Exerted on a Rotator under Illumination of a Vortex Beam
Optical Torque Exerted Rotator Illumination Vortex Beam
2013/7/3
We investigate the torque on a specially shaped rotator produced by a vortex beam. The formulas for the torque alongx, yandzdirections are derived, and numerically calculation is performed. It is foun...
