✦ Synopsis

We report on the first observation of stimulated Raman scattering (SRS) in a crystal of cubic BaF~2~. All registered Stokes and anti-Stokes lasing sidebands in the visible and near-IR (up to the 41st order) are identified to the single χ^(3)^-promoting vibration mode (ω~SRS~ ≈ 238 cm^-1^) of the crystal. The recorded very broad nonlinear lasing comb (more than one octave spanning) in BaF~2~ opens the possibility for experiments on femtosecond waveform synthesis and other laser comb applications.
