Theory and Experiment of Generating Multi-Bottle Beam with Higher Light-Intensity Gradient
Multi-bottle beam with higher light intensity gradient is generated by superposition of Bessel beam and spherical wave in experiment. The field is analyzed with diffraction theory, and according to the result of simulation by software, multi-bottle beam nearby the focus of spherical wave is obtained. In experiment, Bessel beam and spherical wave are generated by axicon and convex lens, respectively, multi-bottle beam is obtained nearby focus as two light waves superposed on the same axis. Comparison of the intensity distribution of bottle beam (BB) generated by the two methods shows that BB generated by interference of Bessel beam and spherical wave has higher intensity gradient in the dark area, which is superior in particles imprison.
