Your library or personal account may give you access

Abstract

Different orders of Laguerre-Gaussian (LG) beam could form two-dimensional orthogonal basis set for laser beams in free space. The orthogonality of LG beams with the same phase change in azimuthal direction but different in radial direction is experimentally studied.
