A one-year study of nonlinear optical effects in fibers using UV lasers investigated stimulated Raman scattering. Lines were seen due to quartz in fibers and due to organic liquids in liquid-filled capillaries. Benzene formed a waveguide, but in preliminary experiments only 1 was converted to stimulated Stokes scattering. Of particular interest was the discovery of Raman scattering of the Nitrogen laser light from the nitrogen vibrational transitions within the laser itself. Such lines have never been reported before. Of additional interest was the multi-line spectral broadening of the stimulated Raman spectra observed from quartz fibers. The reason for this broadening remains to be investigated. Preliminary experiments were performed and apparatus designed which sets the stage for further research into the higher power UV properties of fibers. Keywords include UV, optical fibers, waveguides, nonlinear optics pulses, and stimulated Raman effect.
