Observation of stimulated Raman scattering in CVD-diamond

We report the first experimental observation of nonlinear laser effect – stimulated Raman scattering (SRS) in the man-made diamond grown from the gaseous phase by chemical vapor deposition (CVD) technique. The multiple Stokes and anti-Stokes generation in the visible and near-IR was excited under nanosecond and picosecond pumping in a 350 $\mu $ thick plate. All the registered Raman induced lasing wavelengths were identified. We classify the CVD-diamond as a promising $\chi ^{(3)}$-active material for Raman laser converters in a record wide spectral range.
