LASERCOM Mitigation Program.

Abstract

The effects of nuclear explosions on the propagation of laser link communicatons systems is treated. Estimates are provided for attenuation by the smoke and soot generated by nuclear weapon induced fires for a series of laser wavelengths. Atmospheric turbulence affecting laser beam coherence is investigated, the enhanced atmospheric brightness from the visible thermal pulse of a low altitude explosion is estimated and preliminary work on the refraction effects through shock fronts is presented. Keywords: Laser propagation; Turbulence; Smoke; Soot; Fireball brightness; Refraction.
