Paper Abstract

We present a novel approach to intrinsically mitigate the heat dissipated in Raman lasers due to the pump-Stokes quantum defect. We explain the principle of this so-called "Coherent Anti-Stokes Raman Scattering (CARS)-based heat mitigation", which is based on decreasing the amount of phonons created in the Raman medium by increasing the ratio of the number of anti-Stokes photons to the number of Stokes photons coupled out of a Raman laser. To illustrate the potentialities of this optical cooling technique, we numerically demonstrate that for mid-infrared silicon-based Raman lasers the heat dissipation can be reduced with at least 35% by the use of CARS-based heat mitigation.
