Abstract
The doughnut beams with charges of 1 to 3 are generated by one and stacking two and three Liquid crystal(LC) spiral phase plates with cell gaps of 7 μm respectively. Theoretically, any charge number can be obtained by the stacking method. High efficiency and flexibility are the advantages of generating doughnut beams by stacking liquid crystal spiral phase plates. The interference of doughnut beam generated by LC spiral phase plate and plane wave has been studied. The numerical simulation results agree with the experiment.
