Spatiotemporal optical vortices with arbitrary orbital angular momentum orientation by astigmatic mode converters

Spatiotemporal optical vortices with arbitrary orbital angular momentum orientation by astigmatic mode converters

We generate a spatiotemporal optical vortex (STOV) with tunable orbital angular momentum (OAM) orientation by a simple lens system. We utilize a cylindrical lens system, which is an astigmatic mode converter, to add longitudinal angular momentum to tilt the purely transverse OAM in an arbitrary dire...
