Abstract
We have developed a methodology that has been successful at predicting key parameters in propagating 1.55 micron laser beams over distances from 10 km to 200 km, including estimating the effectiveness of adaptive optics systems at both end of these links. Key points include use of the different Fried coherence length for both the transmitter and the receiver, increases in those coherence lengths available by adaptive optics and use of the Strehl Ratio to calculate reductions in intensity to be expected. These techniques have been successful in predicting intensities measured in a many experiments, including those where turbulence conditions are well into the saturation regime.
