Optical radiation pressure exerted on the rotator has been analyzed. The optical rotator is transparent and has shape anisotropy that is not bilateral symmetry but rotational symmetry in the horizontal cross section. We performed a quantitative analysis of the torque exerted on the rotator while in a single-beam gradient force optical trap. The maximum torque is obtained when a large proportion of the laser beam is incident to the sides wall. We also found that there is an optimum value of NA at which the maximum torque is generated.
