Determination of the azimuthal and radial mode indices for light fields possessing orbital angular momentum

Not Accessible

Your library or personal account may give you access

Abstract

We demonstrate a powerful method to simultaneously measure both the azimuthal and radial indices of pure Laguerre-Gaussian fields. The shape of the diffracting mask used to determine the mode indices is of little importance.
