Author:Dudley, Angela L; Schulze, C; Litvin, I; Duparré, M; Forbes, ADate:Aug 2013Although many techniques are efficient at measuring optical orbital angular momentum (OAM), they do not allow one to obtain a quantitative measurement for the OAM density across an optical field and instead only measure its global OAM. Numerous ...Read more
Author:Schulze, C; Dudley, Angela L; Flamm, D; Duparré, M; Forbes, ADate:Jul 2013We present the reconstruction of a laser beam wavefront from its mode spectrum and investigate in detail the impact of distinct aberrations on the mode composition. The measurement principle is presented on a Gaussian beam that is intentionally ...Read more
