Abstract
The effect of liquid-crystal spiral phase plates on the generation of doughnut laser beams is studied. Several parameters of the liquid-crystal (LC) are analyzed and carefully selected including birefringence of the LC, thickness, cell gap, type, topographic charge number, and applied voltage. The LC spiral phase plates have been fabricated.
