Topological charge of soft X-ray vortex beam determined by inline holography
Abstract A Laguerre–Gaussian (LG) vortex beam having a spiral wavefront can be characterized by its topological charge (TC). The TC gives the number of times that the beam phase passes through the interval $$[0, 2\pi ]$$ [ 0 , 2 π ] following a closed loop surrounding the propagation axis. Here, the...
