New Manifestation of Nonlinear Properties of Acentric Trigonal LaBGeO$\text{}_{5}$ and Orthorhombic Gd$\text{}_{2}$(MoO$\text{}_{4}$)$\text{}_{3}$ Laser Crystal-Hosts: Multiple Stokes and Anti-Stokes SRS and SHG Due to Cerenkov-Type Phase Matching

We have discussed new optical potentialities in acentric Gd$\text{}_{2}$(MoO$\text{}_{4}$)$\text{}_{3}$ and LaBGeO$\text{}_{5}$ laser crystal-hosts having simultaneously relatively high χ$\text{}^{(2)}$ and χ$\text{}^{(3)}$ nonlinear susceptibilities. In particular, we show experimental results on efficient multiple Stokes and anti-Stokes stimulated Raman scattering and Raman induced four-wave mixing, as well as second harmonic generation with Cerenkov-type phase matching.
