Instantaneous intensity distribution in a focused laser beam at 0.63 microm and 10.6microm propagating through the atmosphere.
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.
