Tunable high order anti-Stokes radiation produced by stimulated Raman scattering

Tunable high order anti-Stokes radiation produced by stimulated Raman scattering in liquid nitrogen is studied experimentally. The light beams of two lasers of different frequencies a ruby laser and tunable dye laser --.are simultaneously focussed in liquid nitrogen and two distinct series of anti-Stokes lines are observed. The dye laser anti-Stokes lines can be changed in frequency by tuning the dye laser. The intensities of the two series of lines are investigated as a function of both ruby and dye laser power, The dye laser anti-Stokes line intensities are found to have a distinct threshold for ruby laser power but no threshold for dye laser power. The experimental results support a two step model in which the ruby laser acts as a pump for molecular vibrations which in turn modulate the dye laser frequency. / Science, Faculty of / Physics and Astronomy, Department of / Graduate
