In J. Opt. Soc. Am. A 29, 169 (2012), Gerçekcioğlu and Baykal presented an investigation of the dependence of the scintillation index of flat-topped Gaussian beams on the exponent α of the power-law-type spectra of non-Kolmogorov turbulence. In particular, they found that the scintillation index reaches a maximum at α3.2. We show that this conclusion is an artifact of their specific calculation, and depends on the choice of the length unit. Gerçekcioğlu and Baykal’s calculations are made for the 3<α<5 range of the spectral exponent. We show that for the homogeneous and isotropic turbulence the correct range is 3<α<4, when Markov approximation is used.
