| 摘 要： | 通过在非线性偏振旋转环形腔中引入一种全光纤化的角度可调的起偏器,简化了被动锁模光纤激光器的结构,通过调节环形腔内的光纤起偏器和1/4波片的角度就能够实现锁模脉冲的输出。基于此简化结构,引入基于单片机的触发反馈电路,控制偏振片和波片的旋转状态,实现了腔内锁模脉冲的自动调节输出,得到平均功率为8mW的、重复频率为5.6 MHz的全自动锁模脉冲稳态输出。

| Abstract: | The configuration of passively mode-locked fiber laser is simplified by introducing an in-line rotatable in-line polarizer into the ring cavity.By adjusting the angle between the polarizer and the 1/4 wave-plate,the passively mode-locked laser is obtained.Based on the simple configuration,an automatically passively mode-locked fiber laser is realized by designing the microcomputer circuits to control the rotation states of the polarizer and the wave-plate.A mode-locked laser with a repetition rate of 5.6 MHz and average output power of 8 mW are obtained. |
