Stimulated Raman Scattering of Intense Laser Radiation in a Nuclear-Disturbed Space Plasma
Abstract
Stimulated Raman scattering of intense laser radiation propagating in a nuclear-disturbed space plasma environment has been investigated. For parameters typical of a single high altitude nuclear explosion (HANE), we propagation due to Raman scattering, particularly for 10 micrometer radiation. 10 micrometer, respectively, and for beam power densities on the order of 100000 W/sq cm. Here gamma is the growth rate for simulated Raman scattering. For the multiple HANE case, approximate growth times 1/gamma about .001 to .01 sec can be achieved for laser wavelengths 1 micrometer 10 micrometer with beam power densities of 100000 W/sq cm. As a result, a single burst HANE is not likely, due to stimulated Raman scattering, to effect the propagation of laser radiation with wavelengths of 10 micrometer and 1 micrometer and power densities on the order of 100000 W/sq cm. However, the multiburst HANE environment may degrade laser propagation due to Raman scattering, particularly for 10 micrometer radiation.
