Paper Abstract

We present different methods to enhance the effectiveness of CARS-based heat mitigation, a novel approach for reducing the quantum-defect heating in Raman lasers. More specifically, we discuss the influence of the CARS-related phase mismatch and of backward Raman scattering on our CARS-based heat mitigation technique and explain how these heat-mitigation-affecting factors should be managed to enhance the effectiveness of our technique. To illustrate the feasibility of obtaining efficient CARS-based heat mitigation, we discuss to what extent the described effectiveness-enhancing methods can be applied to near- and mid-infrared silicon-based Raman lasers. Finally, we numerically demonstrate that for near-infrared silicon-based Raman lasers a heat mitigation efficiency of 15% can be obtained, whereas the corresponding efficiency for their mid-infrared counterparts can be as high as 35%.
