Generally speaking, when we increase the repetition rate of the pulse trains of erbium doped fiber laser by rational harmonic mode locking, the amplitude of the pulse trains would not equal as a result. This phenomenon must usually be improved by the use of the other element and setup in the previous thesis. In this thesis we use a new method to increase the repetition rate and improve the unequal pulse trains amplitude caused by rational harmonic mode locking only by changing the DC bias voltage of AM modulator in the cavity.
一般来讲，在利用主动约分谐波锁模来提高掺铒光纤雷射的脉冲重复率的时候，也会造成脉冲序列的振幅不等高性，而文献上解决这个问题的方法都必须利用其他元件和机制来改善，但本论文使用一种方法来提高脉冲重复率及改善因约分谐波锁模所造成的脉冲不等高性，而且仅仅只改变共振腔内的AM调变器之DC Bias就可达到这个目的，而不必像文献上所说的依赖其他元件。
An external signal is necessary in the locking process of the traditional multiplying delay-locked loop. It is used to set total delay of the cyclic delay line in acquisition range of the phase detector, or the whole loop would be out of control. The output clock range of the clock synthesizer using cyclic pulse generation technique is limited by the acquisition range of the PD, and the clock synthesizer could not change its output clock frequency from low to high.
传统的倍数延迟锁定回路(Multiplying Delay-Locked Loop，MDLL)的锁定行为，必须先利用一个外部重置讯号将全部延迟调整到最小延迟，再逐渐增加延迟来锁定回路，这是为了避免循环式延迟线所产生的全部延迟超过了相位侦测器的有效捕捉范围，使延迟锁定回路的负回授机制无法回复至其近似锁定状态，因此产生的时脉无法由低操作频率转换至高操作频率，且输出频率范围受到限制。
