Abstract:
A new pattern of mask for probing the azimuthal and radial indexes of Laguerre-Gaussian(LG) beams is presented.The analysis formula describing the intensity distribution of Laguerre-Gaussian beams after passing through the mask is derived.Based on this formula,the intensity patterns for different azimuthal and radial indexes are obtained via numerical simulations.It,s indicated that for each pair of azimuthal and radial indexes,there is a defined intensity pattern in the observed plane,according to which th...
