25 September 2007Turbulence effects on laser propagation in a marine environment
Our objective is to determine the fraction of a propagated laser beam that will arrive at a receiver after traversing
a 7.1 kilometer near-ocean-surface path. A multi-year experiment has been conducted in 2005 and 2006 to study
near-surface propagation over water at Zuniga Shoal in San Diego. To quantify the effects of turbulence, we
used a saturation-resistant scintillometer to measure the refractivity structure parameter C2/n. A meteorological
buoy located near the mid-path point collected meteorological data which was used as input data for an optical
turbulence model NSLOT. In addition for some of the test period there was also laser propagation data collected
from a 1.064μm laser on the same path.
We compare model predictions with the incoherent scintillometer data and the coherent laser propagation
data.
