Ad. Papayannis et al., GENERATION OF UV AND VIS LASER-LIGHT BY STIMULATED RAMAN-SCATTERING IN H-2, D-2, AND H-2 HE USING A PULSED ND-YAG LASER AT 355 NM/, Applied physics. B, Lasers and optics, 67(5), 1998, pp. 563-568
The stimulated Raman scattering (SRS) technique has been used for upwa
rd and downward shifting of the third harmonic of a pulsed Nd:YAG lase
r (10-105 mJ at 355 nm) into the 274-503 nm wavelength region. Experim
ental results on Stokes and anti-Stokes conversion efficiencies of the
for ward SRS in hydrogen (H-2), deuterium (D-2), and mixtures of hydr
ogen and helium (H-2/He), versus Raman gas pressure and input pump ene
rgy of the pulsed Nd:YAG laser at 355 nm, are reported. Photon convers
ion efficiencies of 50% and 27% are achieved at the first Stokes lines
(S-1) in H-2 and D-2, respectively. As a result, ultraviolet and visi
ble laser light (274-503 nm) was generated with energies ranging from
a few mJ up to several tens of mJ.
