锁模技术 Mode-locking
（重定向自Femtosecond laser）
锁模是光学里一种用于产生极短时间激光脉冲的技术，脉冲的长度通常在皮秒（10秒）甚至飞秒（10秒）。
该技术的理论基础是在激光共振腔中的不同模式间引入固定的相位关系，这样产生的激光被称为锁相激光或锁模激光。这些模式之间的干涉会使激光产生一系列的脉冲。根据激光的性质，这些脉冲可能会有极短的持续时间，甚至可以达到飞秒的量级。

Mode-locking 锁模技术
（重定向自Femtosecond laser）
Mode-locking is a technique in optics by which a laser can be made to produce pulses of light of extremely short duration, on the order of picoseconds (10 s) or femtoseconds (10 s).
The basis of the technique is to induce a fixed-phase relationship between the longitudinal modes of the laser's resonant cavity. The laser is then said to be 'phase-locked' or 'mode-locked'. Interference between these modes causes the laser light to be produced as a train of pulses. Depending on the properties of the laser, these pulses may be of extremely brief duration, as short as a few femtoseconds.
