Abstract

The method of estimation of Cn2 of laser mixture turbulent flow is proposed based on experimental dependencies of amplitude of gas pulsation on spatial pulsation scale. The connection between degree of nonequilibrium and C,2 magnitude is shown. The boundaries of inertial and viscosity ranges are determined. The estimation of Cn2 is within (3 .. . 14). 10 15 cm2/3 as dependence of gas- discharge current.
