- We experimentally demonstrate that a femtosecond frequency comb laser can be applied as a tool for long-distance measurement in air. 本文在实验是第一次报道了利用飞秒激光频率梳来测量距离。
- The frequency comb is generated by a laser that produces a series of veryshort, equally spaced pulses of light (like the teeth of a comb) across a broadspectrum of frequencies. 这个频率梳理装置由一束产生一系列非常短，空间上平均分布（就好象梳齿一样）、频率上广泛分布的光脉冲产生的。
- Two additional features of the pulses emitted by mode-locked lasers are keys to the development of optical frequency combs. 锁模雷射所放出的脉冲另有两个特徵，成为发展光频梳的关键。
- Jun Ye, Steven Cundiff and John Hall bring different backgrounds to their collaboration on developing and applying femtosecond optical frequency combs. 叶军、康帝夫以及霍尔各有不同的背景，但是一起合作发展及应用飞秒光频梳。

- The attosecond pulse train which are consecutive pulses with same carrier envelope phase can push optical frequency combs in the visible and near infrared wavelength to extreme ultraviolet regions. 利用脉冲间具有相同载波包络相位的阿秒脉冲序列能把可见光波段的光学频率梳向极紫外波段扩展；
