Figure 5

Experimental results of the light capsules.

(a–c) Three typical intensity cross-sections of equal interval near the imaging plane and (d) corresponding profile of the generated light capsule employing zero-order modified Bessel-Gauss beam. (e–g) The measured transverse intensity profiles of a high-order modified mode (m = 1, l = 1) along optical axis. (h) The x-z profile of the generated bottle-hollow beam. σ = 2.5 and ω0 = 200 μm in experiments.
