WebThe dual focus property of focused circularly polarized ring Airy beam (RAB) under the action of tightly focused lens is demonstrated in this paper. The radiation forces at two foci of tightly focused RAB are calculated, the numerical results show that the particle could be longitudinally and transversely trapped at the two foci. WebSep 1, 2015 · The beam-clipping-induced increase in divergence angle for the green and blue beams is negligible. Although the blue and green laser diodes are located at x = d LD and x = −d LD, respectively, due to the smaller beam widths w ′ y in the reference plane, no significant beam clipping can be observed. 3.3. Optimized package for the MEMS laser ...
