OPTICAL CLEARING AND SHIELDING WITH FAN-SHAPED VORTEX BEAMS

Optical clearing and shielding with fan-shaped vortex beams

Pellet Pouch 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 sp
