Abstract

一种基于微环谐振腔的多倍频锁模激光器，包括一次通过腔内单模光纤（7）连接的第一波分复用器（12）、掺铒增益光纤（13）、第二波分复用器（14）、光隔离器（2）、偏振控制器（3）、四端口微环谐振腔（4）和光延迟线（6），其中两个波分复用器（12，14）的输入端分别设置有泵浦光源（11，15）。激光器的重频可以微环谐振腔的自由光谱范围为步长进行调节，从而提升目前基于耗散四波混频效率锁模激光器的应用灵活性。

Description

基于微环谐振腔的多倍频锁模激光器 技术领域
本发明涉及一种锁模激光器，具体涉及一种基于耗散四波混频效应的超高重频锁模激光器，更具体的涉及一种基于微环谐振腔的超高重频锁模激光器，且其脉冲速率能以腔内微环谐振腔自由光谱范围为步长自由调节。
背景技术
通常高速光脉冲信号可以由锁模激光器和使用高速光电调整光波产生，后一种方案受限于光调制器和电信号产生器带宽，目前只能达到数十吉赫兹，并且其成本随着速率的提升大幅度的增加。而锁模激光器无需高频电子器件，其具有结构简单、成本低廉、稳定性高等优点，在光通信、光学传感、超连续谱产生等技术研究和工业领域有着极为重要的应用。特别是高重频的多倍频锁模激光器在光通信、高分辨率的光子模数转换、光频梳等领域有着极为重要的应用。
通常光纤激光器的重频只有几兆到几十兆赫兹，不利于其在光通信等需要超高重频脉冲方面的应用。为提升光纤锁模激光器的重频，已有几种解决方案：一是通过缩短激光器的腔长，提升激光腔的模式间隔的方法，利用该方案可以得到超高10GHz重频的光脉冲，然而继续缩短腔长将无法得到足够的腔内增益，因此无法产生实用的光脉冲，且其重频随着激光腔的确定而锁定，无法进行调节。第二种方案是基于耗散四波混频效应的锁模激光器，该类激光器可以实现THz以上重频的锁模脉冲，但其往往存在多纵模不稳定性，无法实际应用，虽然其重频可以通过调节腔内滤波器自由谱范围来改变，但是很难实现速率的精确倍频。第三种方法是采用谐波锁模的方法，已报道的被动谐波锁模可以产生数十吉赫兹的光脉冲，主动谐波锁模激光器甚至可以产生数百吉赫兹的光脉冲，然而谐波锁模激光器容易受到不同谐波模式的干扰，产生时间抖动和幅度波动，此外主动锁模激光器还受限于射频信号，成本高；该方法理论上可以实现脉冲速率的倍频，然而实现超高重频时其谐波阶数很高，在实际操作中很难实现，且对控制系统要求极为严格。
