In our recent publication, we have examined the intensity fluctuations of flat-topped beam in non-Kolmogorov weak turbulence [J. Opt. Soc. Am. A29, 169 (2012)10.1364/JOSAA.29.000169JOAOD60740-3232] in which our comparison of the scintillation indices in the Kolmogorov and in various non-Kolmogorov turbulences was based on the same structure constant, no matter what power law the non-Kolmogorov spectrum takes. In such choice of the fixed structure constant, which is also being used by many researchers in the field [Opt. Express18, 451 (2010)10.1364/OE.18.000451OPEXFF1094-4087; Proc. SPIE6747, 67470B (2007)10.1117/12.737118PSISDG0277-786X; Opt. Commun.285, 880 (2012)], we have found that the variation of the scintillation index against non-Kolmogorov power law exhibits a peak at the worst power law, which happens to be smaller than the Kolmogorov power law of 11/3. Charnotskii commented [J. Opt. Soc. Am. A.29, 1838 (2012)JOAOD60740-3232] on our paper. In this paper, in our to reply to Charnotskii’s comment, we have re-evaluated the scintillation index of flat-topped beam in non-Kolmogorov weak turbulence by employing our recently reported equivalent structure constant [Opt. Lett.36, 4554 (2011)10.1364/OL.36.004554OPLEDP0146-9592] and re-compared the intensity fluctuations in Kolmogorov and in non-Kolmogorov turbulences. As the result of such re-comparison, the worst power law is observed to disappear.
