摘要

我们展示了脉冲宽度为 623 fs、基频重复率为 783 MHz 的掺铒全光纤环形激光器。通过使用碳纳米管可饱和吸收体，实现了相对较低的 108 mW 自启动泵浦阈值。得益于全有源光纤腔体设计，该激光器占地面积小于 10 cm × 10 cm，结构非常紧凑。低相对强度噪声和长期稳定性测试证实了其稳健的锁模功能。我们提出了一种利用紧凑稳定的全主动光纤环形振荡器产生高重复率飞秒光脉冲的新方案。

783 MHz fundamental repetition rate all-fiber ring laser mode-locked by carbon nanotubes

We demonstrate a 783 MHz fundamental repetition rate mode-locked Er-doped all-fiber ring laser with a pulse width of 623 fs. By using carbon nanotubes saturable absorber, a relatively low self-starting pump threshold of 108 mW is achieved. The laser has a very compact footprint less than 10 cm × 10 cm, benefiting from the all-active-fiber cavity design. The robust mode-locking is confirmed by the low relative intensity noise and a long-term stability test. We propose a new scheme for generating high repetition rate femtosecond optical pulses from a compact and stable all-active-fiber ring oscillator.
