本文首次报道了用连续激光泵浦喇曼激活介质，在腔内实现了高效的四波混频。在高精细度腔中，控制腔内色散以满足相位匹配，可以显著增强反斯托克斯辐射。这一过程是在远远超出小信号近似的区域中观察到的，表明分子调制产生的锁相边带。这指出了一种新的方法，即在超过10 THz的频率下工作的光调制器和锁模激光器。
A highly efficient intracavity four-wave mixing in a Raman-active medium pumped by a continuous-wave laser is first demonstrated. Managing the intracavity dispersion to satisfy the phase matching in a high-finesse cavity substantially enhances the anti-Stokes emission. This process is observed in a region far beyond small signal approximation, indicating the generation of phase-locked sidebands arising from molecular modulation. This points to a novel approach of an optical modulator and mode-locked laser operating at a frequency of more than 10 THz.
