Optical bottle beam

WebAnother key advantage over laser beam processing is the coupling efficiency of the EB with the deposited material. For optical energy such as a laser beam, the reflectance for … 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.
