Abstract

A Raman-active crystal, lanthanum tungstate doped with praseodymium (Pr) ions, was grown to facilitate the selection of the order of Stokes waves in stimulated Raman scattering. Absorption of the second Stokes wave by the Pr ions suppressed conversion to higher-order Stokes waves, resulting in efficient energy conversion to the first Stokes wave.
