Paper Abstract

We analyze the properties of light beams carrying phase singularities, or optical vortices. The transformations of topological charge during free-space propagation of a light wave were presented in a theory and experiment. We report theoretical calculations of orbital angular momentum density (AMD) in a of combined beam, which is a superposition of LG01, LG10 and LG00 modes with different relative phase shifts and intensity ratio. We show that the total orbital angular momentum in a combined beam is constant during the propagation, in spite of any variation in the absolute value of AMD.
