We propose and demonstrate a new method for creation of fan-shaped optical vortex beams by rational phase modulation and assembly based on a well-known conical vortex phase. Our design is different from the previously proposed method for generation of power-exponential vortex beams. Such unconventional vortex beams consist of multiple spiral beam filaments (as the fan blades). and the... https://www.unitedssports.shop/product-category/hockey-protective-shoulder-pads-junior/
