Abstract
Laguerre–Gauss vortex beams carrying different topological charges are generated from Hermite–Gauss laser beams emitted by a gas laser, and their phase properties are explored by studying their interference with a plane wave. Interference of two Laguerre–Gauss vortex beams carrying equal but opposite topological charge is also studied by using a modified Mach–Zehnder interferometer. Experimentally recorded intensity profiles are in good agreement with the theoretically expected profiles.
