Experimental Realisation of a π/2 Vortex Mode Converter for Electrons Using a Spherical Aberration Corrector
T. Schachinger, P. Hartel, P. -H. Lu +6
In light optics, beams with orbital angular momentum (OAM) can be produced by employing a properly-tuned two-cylinder-lens arrangement, also called /2 mode converter. It is not…

/2 Mode Converters and Vortex Generators for Electrons
Christian Kramberger, Stefan Löffler, Thomas Schachinger +3
In optics, mode conversion is an elegant way to switch between Hermite Gaussian and Laguerre Gaussian beam profiles and thereby impart orbital angular momentum onto the beam and to…
