The optical force distribution was theoretically calculated along the axial and radial directions with different beam waists. (a) The axial force distribution with a beam waist of 2 µm; (b) the radial force distribution with a beam waist of 2 µm; (c) the axial force distribution with a beam waist of 4 µm; (d) the radial force distribution with a beam waist of 4 µm.
