Stimulated Raman scattering in a 532 nm Nd:YAG laser pump hydrogen Raman shifter with a capillary waveguide
Abstract
Stimulated Raman scattering (SRS) in hydrogen gas using a capillary waveguide (CWG) is reported. Six (6) Raman lines in the wavelength range 283.7 nm – 955.5 nm are generated using linearly polarized laser light from the second harmonic (532 nm) of a pulsed Nd:YAG laser. The threshold power for the generation of the first Stokes (S1) decreased by almost 65%. Conversion efficiency of the Raman lines increased in the presence of the CWG.
