The Design And Construction Of A Long-Distance Atmospheric Propagaion Test Chamber

ENS Robert A. Torrealba, USN

Abstract: This thesis consists of two parts. The first part involved using a laser modeling tool called ANCHOR to compare two 100kW lasers in a potential operational theater, one with at a wavelength of 1.0642 μm, and the other with a wavelength of 1.5314 μm. This modeling illustrated that the effective range of the laser can be greatly reduced due to haze or humidity (or both), depending on its lasing wavelength. The second part of this thesis describes a multi-pass spectroscopic experimental setup that employs a White cell that can be used to measure atmospheric extinction coefficients in a controlled manner. The first results from this setup produced consistent, comparable atmospheric extinction values.
