Abstract

In this work, we demonstrate a diamond Raman oscillator at high average powers, and we study in detail the influence of resonator length on the spectral features of the output beam. Additionally, we investigate the occurrence of parasitic nonlinear effects such as four-wave mixing, Brillouin and anti-Stokes Raman scattering. Furthermore, we propose a method to suppress Brillouin scattering in diamond Raman oscillators and thus allow for further power scaling. An etalon is used to decouple parasitic spectral components, achieving a high purity output spectrum which is tested at different cavity lengths and its performance compared with an ordinary mirror.
