Comparing the experiment and the theoretical prediction for the WDF of the LG mode of order : (a) the WDF of the ideal mode (solid black) and of the measured in an experiment laser beam (dashed yellow) with the corresponding error band; the frequency histogram of the deviation of the fitting parameters (yellow) and (blue) in the inset at the right-bottom, Equation (25), supplied to the model (21), and resulted from the fitting procedure: 1000 synthetic data sets have been generated and fitted with the model, mentioned above; for each run, the deviation between the supplied and fitted parameters has been calculated.
