Generating Petal Beams using LG modes and Vortex Lens

[Watson Ly]

Hi,

I was trying to simulate generating petal beams by combining 2 LG modes and vortex phase plates.

I should be able to generate donut beams using a LG00 Mode beam and passing it through the vortex plate, but I still get a regular Gaussian beam power profile in the spatial visualizer.

The Phase looks correct, but if there’s a phase singularity in the origin, shouldn’t there be no power there as well?

I can create donut beams using LG01 and no Vortex phase plate, but when combining, the output power profile is still incorrect.

Thanks,
Watson
