A comparison of the spectroscopic parameters of Raman-active vibronic modes in various crystalline materials with a view to the use of these crystals for stimulated Raman scattering (SRS) is presented. It includes data on the Raman frequency shift, linewidth, integral, and peak Raman scattering cross sections. For steady-state SRS the highest Raman gain coefficient has been proved to be in barium nitrate and sodium nitrate crystals; for transient SRS it is expected to be in lithium niobate and tungstate crystals. Barium tungstate and strontium tungstate are proposed as new highly efficient Raman materials for both SRS cases.

We present a highly efficient ring-cavity all-solid-state BaWO Raman laser generating at both the long-shift (ν=925  cm) and short-shift (ν=332  cm) Raman lines under external picosecond synchronous pumping at the wavelength of 1063 nm. Very high slope efficiencies and output pulse energies of 68.8% and 103 nJ at the ν-shifted Stokes wavelength of 1179 nm, and 38.6% and 53 nJ at the (ν+ν)-shifted Stokes wavelength of 1227 nm have been achieved. Self-mode locking of the (ν+ν)-shifted Stokes field under intracavity pumping by the ν-shifted Stokes field allowed to realize 12-fold shortening of the 1227 nm radiation pulse down to 3 ps close to the shorter dephasing time of the ν Raman line at the output pulse peak power 1.5 times higher than the pump peak power.
