Generation of High-Energy Photons with Large Orbital Angular Momentum | |
|
||
|
Usually, photons are described by plane waves with a definite 4-momentum. In addition to plane-wave photons, "twisted photons" have recently entered the field of modern laser optics; these are coherent superpositions of plane waves with a defined projection (h/2p) m of the orbital angular momentum onto the propagation axis, where m is integer. An experimental realization exists for states with projections as large as m = 200. In recent papers we had shown that it is possible to produce high-energy twisted photons by Compton backscattering of twisted laser photons off ultra-relativistic electrons. Such photons may be of interest for experiments in atomic and nuclear physics in previously unexplored experimental regimes.
