Recently we demonstrated the ability of managing the OAM generated by dedicated optics, by adding and subtracting, manipulating and analyzing it. Now, we can prove off-axis capabilities going beyond standard treatment, In my talk, I will present some recent results on selected systems.
Photon spin-orbit conversion occurs when a photon's spin angular momentum is converted to orbital angular momentum. This has been observed in the infrared and visible light regimes when scattering from subwavelength birefringent structures. However, the fabrication of such structures for x-ray wavelengths is not feasible. Here, we propose that x-ray spin orbit conversion (XSOC) can be achieved...
Production and manipulation of orbital angular momentum (OAM) of coherent soft X-ray beams is demonstrated utilizing consecutive diffractive optics. OAM addition is observed upon passing the beam through consecutive fork gratings. The OAM of the beam was found to be decoupled from its spin angular momentum (SAM). We argue that practical implementation of angular momentum control by consecutive...
