In single crystals of the beryllium silicate Be 2 SiO 4 with trigonal symmetry R 3 ¯ , known also as the mineral phenakite, χ (3) ‐nonlinear lasing by stimulated Raman scattering (SRS) is investigated. All observed Stokes and anti‐Stokes lasing components are identified and ascribed to a single SRS‐promoting vibration mode with ω SRS ≈876 cm −1 . With picosecond single‐wavelength pumping at one micrometer the generation of an octave‐spanning Stokes and anti‐Stokes comb is observed.
