Cavity dumping of an all-fiber laser system is demonstrated. The active element is a pulse-picker with nanosecond rise time consisting of a microstructured fiber with electrically driven internal electrodes. The device is used for intracavity polarization rotation and dumping through a polarization splitter. The optical flux is removed from the cavity within one roundtrip and most of the amplified spontaneous emission, spiking and relaxation oscillation that follow during the gain recovery phase of the laser are blocked from the output signal.
演示了全光纤激光系统的腔倒空。有源元件是一个上升时间为纳秒级的脉冲拾取器，由带有电驱动内部电极的微结构光纤组成。该器件用于腔内偏振旋转，并通过偏振分束器进行腔倒空。光通量在一个往返周期内从腔内移除，并且在激光增益恢复阶段随之产生的大部分放大自发辐射、尖峰和弛豫振荡都被阻止进入输出信号。
