Abstract:
Experimental results from investigations of instantaneous intensity distributions in focused laser beams at 0.63 microm and 10.6 microm at a distance of approximately 5 km are presented and discussed. At 0.63 microm the beam pattern is broken into several diffraction-scale spots because focusing is saturated. At 10.6 microm the beam pattern is almost uniform. This is valid for beam dimensions smaller than the correlation length of the amplitude.
