Phase Conjugation Scaling for High Energy Lasers.

Abstract

Phase conjugation of both continuous and pulsed 10.6 micron lasers by stimulated Brillouin backscattering (SBB) has been attempted. Because of various technical difficulties, conclusive evidence of SBB was not found. However, theoretical studies in this project supported further the promise of SBB for obtaining diffraction-limited beams from high power infrared lasers. Several novel schemes for realizing 10 micron waveguides of several meters length were explored experimentally. Keywords: High energy lasers; Phase conjugation; Stimulated Brillouin scattering; and Infrared waveguides.
