Abstract

The stimulated Raman scattering gain coefficient in KDP/DKDP crystals for any orientation with respect to the crystal axis, propagation and polarization of the pump beam can be estimated using a) the spontaneous Raman scattering cross section of the material, b) the spectral profile of the Raman line and, c) the Raman scattering tensor. Of particular interest in ICF class laser systems are the parasitic Transverse Stimulated Raman Scattering effects. In this work we provide experimental results that help advance our ability to estimate these effects at operational conditions for second, third and fourth harmonic generation.
