Orbital angular momentum of an elliptically symmetric laser beam after passing an elliptical spiral phase plate
We obtain a simple closed expression for the normalized orbital angular momentum (OAM) (OAM per unit power) of an arbitrary paraxial light beam of an elliptical cross-section, diffracted by an elliptical spiral phase plate (SPP), rotated by an arbitrary angle around the optical axis. Note that the e...
