Optics in Atmospheric Propagation and Adaptive Systems VI
The experimental study of laser beam propagation in turbulence is relevant to fields such as adaptive optics and optical communications. Turbulence sensing for astronomical purposes requires a convergent laser beam adequately focused on the sodium mesospheric layer. Free Optical communications ground-to-satellite usually are based on divergent laser beams travelling partially through the atmosphere. We present several measurements of the gaussian beam radius for divergent and convergent laserdoi:10.1117/12.511563 fatcat:gy6ufxbxpjdt5ommn2eds6jltm
