WebFeb 23, 2024 · An optical beam that has a line of null on-axis intensity surrounded in all directions by relatively higher intensity regions is named optical bottle beam (Arlt and Padgett 2000). Bottle beams create an optically dark area that may be applied to measure a nanoparticle’s dynamics in the dark field, for example, cold atoms (Cacciapuoti et al ... WebThe beam is a superposition of two Laguerre–Gaussian modes that are phased so that they interfere destructively to give a beam focus that is surrounded in all directions by regions of higher intensity. Beams of this kind will have applications in the optical trapping of macroscopic objects or atoms; hence the term optical bottle beam. WebOct 1, 2003 · An optical bottle is an intensity null surrounded by a region of high intensity. Multiple optical bottles can act as localised trapping sites offering the possibility of creating a three-dimensional array of optical bottles which are scattered throughout the beam propagation volume.
