Abstract

We report on the first experimental observation of stimulated Raman scattering (SRS), stimulated low-frequency Raman scattering and multiphoton excited negatively-charged single nitrogen-vacancy (NV-) centers luminescence in ethanol suspension of submicron diamond particles obtained at high pressures and temperatures (HPHT). The Stokes and anti-Stokes SRS components with a frequency shift of 1332 cm−1, corresponding to the fundamental optical mode of diamond crystal were observed. The spectral characteristics and energy thresholds of the studied processes were determined.
