摘要
Abstract
We propose a novel single-beam multiple 3D optical trapping scheme using higher polarization order axially-symmetric polarized beams in an aplanatic focusing system.We calculate numerically the intensity distribution near the focus which presents a multi-focus-spot pattern and provides the possibility of multiple optical trapping.We also calculate the corresponding gradient force distribution near the focus.Finally we introduce a 3D optical chain by combining the single-beam system with a single diffractive optical element.
