Abstract:
Feasibility of the effective correlation analysis of spatial Gauss-Laguerre (GL) modes is experimentally shown. The laser beam of desired transverse-modal composition was generated using a binary-phase diffractive optical element (DOE). A 24-channel phase DOE was employed as a matched spatial filter. Ratio of the correlation signal to the average background noise is 42.
