The scattering force \({\mathop{F}\limits^{\rightharpoonup }}_{scat}\) (a–c) and total longitudinal optical forces \({\mathop{F}\limits^{\rightharpoonup }}_{grad,z}\) + \({\mathop{F}\limits^{\rightharpoonup }}_{scat}\) exerted upon a Rayleigh dielectric sphere for the focused different ordered HsGBs near the focus at several planes: (a,d) x = 0, (b,e) x = 0.1 μm, and (c,f) x = 0.2 μm. The remaining parameters are P₀ = 100 mW, f = 25 mm, w₀ = 10 mm, n₂ = 1.33, n₁ = 1.59 and a = 25 nm.
