An optical system comprising a c-cut uniaxial crystal positioned between two axicons and illuminated by a Gaussian or a Laguerre–Gauss mode was used to demonstrate the generation of various vector ...

Coherent beam combining technology applied to multiple vortex beams is a promising method to generate high-power vortex beams. We utilize the coherent combination of multiple Laguerre-Gaussian beams ...

(Nanowerk News) A new publication from Opto-Electronic Advances ("Tailoring electron vortex beams with customizable intensity patterns by electron diffraction holography"), discusses tailoring ...
