Electron vortex beams with high quanta of orbital angular momentum.
Electron beams with helical wavefronts carrying orbital angular momentum are expected to provide new capabilities for electron microscopy and other applications. We used nanofabricated diffraction holograms in an electron microscope to produce multiple electron vortex beams with well-defined topological charge. Beams carrying quantized amounts of orbital angular momentum (up to 100ħ) per electr...
متن کاملNonlinear Beam Shaping with Plasmonic Metasurfaces
We present here a method for generating second-harmonic beams with tailored beam profiles using nonlinear metasurfaces based on split ring resonators. By manipulating both the phase and the amplitude of the quadratic nonlinear coefficient locally, at the single inclusion level, the emitted secondharmonic wavefront is perfectly controlled. These concepts are demonstrated experimentally by the fa...
متن کاملCreation of Optical Vortices Using an Adjustable Spiral Phase Plate and Computer-Generated Holograms
An adjustable spiral phase plate and computer-generated holograms were investigated as methods for creating optical vortices. The phase plate was created by cutting a plastic microscope cover slip from a corner to its center and separating the resultant tabs by inserting a uniformly thick wedge between them. The computer-generated holograms were designed by mathematically interfering an oblique...
متن کاملNormal modes and mode transformation of pure electron vortex beams.
Electron vortex beams constitute the first class of matter vortex beams which are currently routinely produced in the laboratory. Here, we briefly review the progress of this nascent field and put forward a natural quantum basis set which we show is suitable for the description of electron vortex beams. The normal modes are truncated Bessel beams (TBBs) defined in the aperture plane or the Four...
متن کاملDynamic wavefront and polarisation control for ultrashort-pulse laser microprocessing
New developments in wavefront and polarisation control for ultrashort-pulse laser microprocessing are presented. Two Spatial Light Modulators are used in combination to structure the optical fields of a picosecond-pulse laser beam, producing vortex wavefronts and radial or azimuthal polarisation states. Demonstration of multiple first-order beams with vortex wavefronts and radial or azimuthal p...
