Figure 4

(a) Explanation of the light intensity distribution in a spot. This example corresponds to a 4-beam interference pattern. The concentric blue, green, and red circles represent \(\left|{\varvec{r}}\right|=1.18, 1.83,\) and \(2.59\) μm, respectively. An explanation of the deflection angle \(\theta \mathrm{^{\prime}}\) of the radiation force \({\varvec{F}}\) at \(R(r,\theta )\) is shown. (b–d) Variation of the light intensity in a Gaussian spot and 4- and 6-beam interference patterns versus declination angle \(\theta\) and \(\left|{\varvec{r}}\right|\), respectively.
