✦ Synopsis

Multiple stimulated Raman scattering (SRS) and cascaded
nonlinear χ^(3)^ ↔ χ^(2)^
generation in tetragonal non-centrosymmetric Li~2~B~4~O~7~
crystal were observed under picosecond
Nd^3+^:Y~3~Al~5~O~12~ laser excitation. All registered
Stokes and anti-Stokes lasing components in the visible and
near-IR were identified and attributed to the SRS-promoting
vibration modes of the studied crystal. We classify the
Li~2~B~4~O~7~ crystals as a promising media for up- and
down-Raman laser-frequency converters. In the work a brief review
of nonlinear-laser properties of SRS-active borate crystals is
given.

Large single crystals of the compound LaBO~2~MoO~4~, undoped and doped with Nd^3+^ ions, were grown. Their multi-wavelength Stokes and anti-Stokes picosecond generation, nonlinear-laser effects, and neodymium IR luminescence were investigated. We classify these crystals as a promising material for R
