Description
Advances in X-ray diffractive optics with nearly arbitrary beam-structuring capabilities open new possibilities for the use of X-rays in probing complex electronic structures in matter. ALS-U and the increased coherent flux from diffraction-limited synchrotrons make the potential for innovative methods with these optics even more attractive. One demonstrated result of tailoring the intensity and phase structure of X-rays is the creation of “twisted X-rays”, or X-ray vortices with orbital angular momentum (OAM) of arbitrary integer multiples of h-bar.
