Abstract We present a novel technique that intrinsically mitigates the quantum-defect heating in Raman lasers. The basic principle of this so-called “coherent anti-Stokes Raman scattering (CARS)-based heat mitigation” is to suppress the phonon creation in the Raman medium by increasing the number of out-coupled anti-Stokes photons with respect to the number of out-coupled Stokes photons. We demonstrate with the aid of numerical simulations that for a hydrogen and a silicon Raman laser, CARS-based heat mitigation efficiencies of at least 30% and 35%, respectively, can be obtained.
