Abstract
Experimental results are presented for the statistics of 0.6328-μm laser irradiance fluctuations for multiple-pass propagation through a laboratory-simulated atmospheric turbulence of strength and the smallest scale size l0 = 2.74 mm. The coefficients of variation γ0, skewness γ1, and excess γ2 of irradiance fluctuations are plotted as a function of path length. From the plots of γ2 vs γ1 for various values of in different regions within the turbulence, the following forms of the probability distribution functions for the irradiance fluctuations are considered: lognormal, Rice-Nakagami, m distribution, gamma (and exponential), and K distribution. We have also demonstrated the characteristic feature of −8/3 power law behavior of power spectrum and the shift of Tatarski's peak frequency in the case of strong turbulence.
