Abstract :
The stimulated Raman effect in methane was investigated both theoretically and experimentally. An experimental setup was used to optimize the Raman conversion of a 1.06-μ laser source into a wavelength of 1.54 μm in pressurized methane. Efficient conversion (up to 45% efficiency) is accomplished when using a full-resonator configuration for the Stokes wavelength. A numerical model is introduced, describing the Raman conversion process in the backward and the forward directions. Half-resonator and full-resonator configurations are studied. The results of the numerical model are in agreement with the experimental results
