Abstract

Based on the traditional iterative algorithm, phase-only element was used to generate vortex beams with two Orbital Angular Momentum (OAM) modes in different energy ratios. The use of pure phase modulation results in the presence of undesired OAM modes in the vortex beams, which follow a pattern. Additionally, the number of initial input parameters in the iterative algorithm affects the energy ratio between the two OAM modes. By adjusting the number of initial input parameters, a more desirable relative power distribution can be achieved.
