我们演示了两个低噪声750 MHz YTTERBIUM纤维频率梳子，它们独立稳定在连续波激光器上。散装电气调节器和单栈压电传感器被用作快速执行器，以稳定各自的空腔长度至杂化击中音符。这两个梳子均表现出与1 s时10（-18）相似的环内频率不稳定性。据我们所知，这是紧密相锁的首次演示（
We demonstrate two low-noise 750 MHz ytterbium fiber frequency combs that are independently stabilized to a continuous-wave laser. A bulk electro-optic modulator and a single-stack piezo-electric transducer are employed as fast actuators for stabilizing the respective cavity length to heterodyne beat notes. Both combs exhibit in-loop fractional frequency instabilities of similar to 10(-18) at 1 s. To the best of our knowledge, this is the first demonstration of tightly phase-locked (
