Paper Abstract

A loss of beam intensity occurs when a laser beam is propagated through shear layers with optical index fluctuations. A new model which uses Fraunhofer diffraction around a sinusoidal phase grating predicts the loss of intensity accurately. The size of coherent structures within the shear layers determines the spacing and the width of the grating. Numerical results agree well with previous experimental results.
