Abstract : The major objective of this program is to experimentally investigate the wavelength-dependence of turbulence effects on optical propagation through the atmosphere, and to relate the results to certain meteorological parameters, theoretical models, and model-independent dimensional analyses. During the third period, the laser, optical, and electronics systems were installed at the new field facility, and successful multiwavelength operation of the overall system was demonstrated. A technique was developed for rapid pointing of the infrared transmitter beams, and other experimental problems were identified and corrected. The resultant facility is uniquely suited to the investigation of the wavelength-dependence of scintillation and saturation, the range of validity of the existing analyses, and the conditions under which the commonly-accepted atmospheric models become inapplicable.
