Abstract

The stimulated Raman scattering (SRS) and four-wave mixing (FWM) processes have been studied in detail in CH4 gas pumped by the third-harmonic of Nd:YAG laser at γ=355 nm. The conversion efficiency and average output energy have been measured for the various Stokes and anti-Stokes lines at different experimental conditions. The threshold input energy at various CH4 pressures has been calculated for the unguided and capillary waveguide Raman cells. The calculated values for the capillary case have been compared with the measured values at different CH4 pressures and the two results are in good agreement.
