Abstract
The stimulated Raman Spectrum (SRS) due to the Raman active symmetric stretching modes (ν1) of vibration of both hydrogen and methane were recorded and a comparative study of their relative intensities as well as the wavelength conversion efficiencies were carried out. It was found that hydrogen showed much higher wavelength conversion efficiency than methane due the seeding of third SRS line at 397.8 into Balmer H-ε line at 397 nm in hydrogen. The input pulse energy dependence on the SRS signal showed a linear dependence for methane and a non linear dependence for hydrogen.
