PROPAGATION OF A LASER BEAM THROUGH A PLANE AND FREE TURBULENT HEATED AIR FLOW: DETERMINATION OF THE STOCHASTIC CHARACTERISTICS OF THE LASER BEAM RANDOM DIRECTION AND SOME EXPERIMENTAL RESULTS

The propagation of waves in a random medium is a very complex phenomena which presents numerous difficulties in its experimental approach, and in its theoretical analysis. In this work, the case of a laser beam direction during its random propagation thro
