Abstract

A monolithic diamond Raman laser is reported. It utilizes a 13mm radius of curvature lens etched onto the diamond surface and dielectric mirror coatings to form a stable resonator. The performance is compared to that of a monolithic diamond Raman laser operating in a plane-plane cavity. On pumping with a compact Q-switched laser at 532nm (16μJ pulse energy; 1.5ns pulse duration; 10kHz repetition-rate; M2 <1.5), laser action was observed at the first, second and third Stokes wavelengths (573nm, 620nm and 676nm respectively) in both cases. For the microlens cavity, a conversion efficiency of 84% was achieved from the pump to the total output power, with a slope efficiency of 88%. This compares to a conversion efficiency of 59%, and a slope efficiency of 74% for the plane-plane case. Total Raman output powers of 134mW and 96mW were achieved for the micro-lens and plane-plane cavities respectively.
