Abstract |
|
|
| The stimulated Raman Spectrum (SRS) due to the Raman active symmetric stretching
modes (?1) 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-" 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. |
