  Optical turbulence is the term that is used being based on the analogy
between hydrodynamic and optical equations. The phenomenon of turbulent photon
filamentation occurs in lasers and other active optical media at high Fresnel
numbers. A description of this phenomenon is suggested. The solutions to
evolution equations are presented in the form of a bunch of filaments
chaotically distributed in space and having different radii. The probability
distribution of patterns is defined characterizing the probabilistic weight of
different filaments. The most probable filament radius and filament number are
found, being in good agreement with experiment.
