Impulsive SRS in tetragonal t-YVO4, t-GdVO4and monoclinic m-LaVO4vanadate host-crystals for Ln3+-lasant ions

Tetragonal t-YVO4, t-GdVO4 and monoclinic m-LaVO4 are widely known as host-matrix materials for Ln3+-lasant ions in high-gain SRS-active crystals. In this study, many phonon impulsive stimulated Raman scattering (ISRS) was excited under femtosecond pumping for these materials. All of the observed χ(3)-non-linear lasing components were attributed to the vibrations of the [VO4]3− structural units of these vanadates. The article gives a short review (in table form) of all known SRS-active crystals with tetragonal zircon-type (ZrSiO4) and monazite-type (CePO4) structure and their observed χ(3)-nonlinear optical effects.
