Abstract

A megawatt-class high energy laser aboard a Navy ship could provide effective self defense against modern anti-ship missiles. The free electron laser is a candidate for use in this mission, and has several advantages over chemical lasers, which have been previously considered. One obvious advantage is wavelength tune-ability of teh FEL-allowing tuning of the laser wavelength to an atmospheric spectral window of minimum absorption. This study reports on analysis performed to select optimum wavelengths for a ship-based FEL in consideration of atmospheric effects. We examine atmospheric absorption, scattering, trubulence, and thermal blooming, and compare their relative importance in optimizing power in the bucket on target for representative scenarios. We also examine the issue of thermal blooming caused by atmospheric aerosol absorption, and examine the relative absorption of open-ocean vs continental aerosols. We find excellent propagation results at 1.625 and 1.047 microns.
