Abstract:

Helium Neon and Helium Cadmium Laser Beams were propagated through a turbulent medium and the Mean Laser Beam Intensity and Power Profiles were measured in the Focal Plane. The parameters effect of ranges of the ratios of integral and micro scales of turbulence to laser beam diameter and ranges of turbulence intensities which are typical of laser cavities are reported. The experimental measurements are compared with analytical predictions of Chernov and Sutton showing that the uncertainty in predicting laser beam spread in the presence of random fluctuations has been reduced by a factor of at least 2.
