Second Stokes generation at 620nm in 2mm long micro-lensed monolithic diamond Raman lasers is reported with 63% conversion efficiency. The Raman intracavity mode radius was found to be half that expected from the ABCD calculations of the resonator mode. Raman gain-guiding mechanism is suggested as an explanation.
