From: Controllable light capsules employing modified Bessel-Gauss beams
Formation condition of optical bottle employing zero-order modified Bessel-Gauss beam and the intensity distributions of light capsule.
(a) Transverse intensity profiles of zero-order modified Bessel-Gauss beams with different parameters of σ = 0.5 (blue line), 1 (red line) and 2 (green line) and the corresponding 1D intensity curves. (b) Longitudinal intensity curves of the zero-order mode for three typical σ. (c) Seven cross-sections with equal separation distances along optical axis of the bottle beam (ω0 = λ and σ = 2) together with the correspongding 1D transverse intensity profiles. (d) The x-z intensity profile of the light capsule formed by zero-order modified Bessel-Gauss beam and its 3D model (bottom).
