摘要：

Characterizing both the radial (p) and azimuthal (& ell;) indices of Laguerre-Gaussian (LG) beams remains a challenge mainly due to their transverse amplitude profiles. We report a simple yet robust method for simultaneously identifying both mode indices using an off-axis parabolic mirror (OPM). The far-field diffraction pattern produced by an incident LG beam on OPM exhibits characteristic spot distributions, which can be analyzed to determine the magnitude and sign of the topological charge, as well as the radial index. Furthermore, we show that this technique exhibits excellent tolerance to beam misalignment. Experimental results show good agreement with numerical simulations.
