Abstract
Section titled āAbstractāSummary form only given. Continuous-wave single-longitudinal-mode (SLM) lasers are an important tool for applications exploiting light-matter interactions. However, mature laser technologies using inversion gain media cover only a limited part of the optical spectrum. Therefore, nonlinear frequency conversion is necessary to reach wavelengths outside this range. Conversion using stimulated Raman scattering can be a simple and robust approach [1], and an SLM diamond Raman laser using a 40 W pump laser has been recently reported [2].Here we present efficient Raman conversion of a SLM Ti:sapphire laser (SolsTiS, M Squared Lasers) outputting 5 W at 790 nm. The pump field was cavity-enhanced in a ring cavity with a 1% transmissive input mirror, which also contained a 5 mm long Brewster-cut diamond crystal (Element Six). Raman lasing within the enhancement cavity occurred for pump powers above 1 W, generating a Stokes field at 893 nm. Stokes output was emitted though the input mirror that had 1% transmission at the Stokes wavelength.
