Abstract:

Calculation code and result of beam profile clipped by d=74mm aperture.
Two cases : input q-parameter is q=5153+i*3478 and q=1187.48+i*4009.39 (at the aperture).
Observation point is 15m away from the aperture.

*code (for MATLAB)
DiffractionModeCalculatino.m : main code
LGmodeM0.m : cylindrically symmetry Laguerre-Gaussian mode function
DiffractionProfile.m : diffraction beam profile function
