研制了一种基于克尔透镜锁模Yb：Y_2O_3陶瓷激光器的15GHz模间距光频梳。商业光谱仪清晰地分辨出各个模式。为了演示光频梳的长期操作，将单个纵模锁相到频率稳定的连续波激光器，并将重复频率锁定到射频标准。据我们所知，15 GHz是克尔透镜锁模激光器和直接飞秒激光器基光频梳的最大模式间隔（重复率）。
A 15-GHz mode spacing optical frequency comb based on a Kerr-lens mode-locked Yb:Y2O3 ceramiclaser has been developed. Individual modes were clearly resolved by a commercial spectrometer. To demonstrate the long-term operation of the optical frequency comb, a single longitudinal mode was phase-locked to a frequency-stabilized continuous wave laser and the repetition rate to a radio frequency standard. To the best of our knowledge, 15 GHz is the largest reported mode spacing (repetition rate) for both a Kerr-lens mode-locked laser and a direct femtosecond laser based-optical frequency comb.
