| Abstract: | We determined, for the first time, the room temperature phonon energy related to the F2g vibration mode (ωSRS(12C) ～ 1333.2 cm–1) in a mono‐crystalline single‐isotope CVD 12C‐diamond crystal by means of stimulated Raman scattering (SRS) spectroscopy. Picosecond one‐micron excitation using a Nd3+:Y3Al5O12‐laser generates a nearly two‐octave spanning SRS frequency comb (～12000 cm–1) consisting of higher‐order Stokes and anti‐Stokes components. The spacing of the spectral lines was found to differ by ΔωSRS ～ 0.9 cm–1 from the comb spacing (ωSRS(natC) ～ 1332.3 cm–1) when pumping a conventional CVD diamond crystal with a natural composition of the two stable carbon isotopes 12C (98.93%) and 13C (1.07%).
