Abstract
Section titled “Abstract”We determined, for the first time, the room temperature phonon energy related to the F 2g vibration mode ( ω SRS(12C) ∼ 1333.2 cm -1 ) in a mono‐crystalline single‐isotope CVD 12 C‐diamond crystal by means of stimulated Raman scattering (SRS) spectroscopy. Picosecond one‐micron excitation using a Nd 3+ :Y 3 Al 5 O 12 ‐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 Δ ω SRS ∼ 0.9 cm -1 from the comb spacing ( ω SRS(natC) ∼ 1332.3 cm -1 ) when pumping a conventional CVD diamond crystal with a natural composition of the two stable carbon isotopes 12 C (98.93%) and 13 C (1.07%).
