Vortex beam array generated by a volume compound fork grating in lithium niobite
Here, we report a generation of vortex beam array based on a micro volume compound fork grating fabricated by a femtosecond laser direct writing technique in lithium niobite crystal. The grating is able to convert a Gaussian laser beam into an array of large number of vortex beams with high purity a...
