ABSTRACT
Abstract. The stimulated Raman scattering (SRS) technique has been used for upward and downward shifting of the third harmonic of a pulsed Nd:YAG laser (10-105 mJ at 355 nm) into the 274-503 nm wavelength region. Experimental results on Stokes and anti-Stokes conversion efficiencies of the forward SRS in hydrogen (H[sub 2]), deuterium (D[sub 2]), and mixtures of hydrogen and helium (H[sub 2]/He), versus Raman gas pressure and input pump energy of the pulsed Nd:YAG laser at 355 nm, are reported. Photon conversion efficiencies of 50% and 27% are achieved at the first Stokes lines (S[sub 1]) in H[sub 2] and D[sub 2], respectively. As a result, ultraviolet and visible laser light (274-503 nm) was generated with energies ranging from a few mJ up to several tens of mJ.
