The shorter the laser pulses, the broader the range of frequencies in the comb.
激光脉冲越短，频率梳的频率范围越宽。
The type of laser used to make the comb is critical to the precision of the ruler.
用来产生光学频率梳的激光的类型对于此频率尺的精度至关重要。
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。
