论文摘要
我们报告了简单，紧凑的锁定型ER掺杂纤维激光器的设计和特征及其在宽带腔增强光谱上的应用。维持振荡器的石墨烯模式锁定极化是热稳定的，并配备了控制重复速率的三个执行器：快速和缓慢的纤维担架，以及金属涂层的纤维部分。这允许将重复率及其稳定化对外部参考源进行广泛调整。通过使用连续过滤的游标光谱法检测到空气中的CO2来证明激光对分子光谱的适用性。
We report the design and characteristics of a simple and compact mode-locked Er-doped fiber laser and its application to broadband cavity-enhanced spectroscopy. The graphene mode-locked polarization maintaining oscillator is thermally stabilized and equipped with three actuators that control the repetition rate: fast and slow fiber stretchers, and metal-coated fiber section. This allows wide tuning of the repetition rate and its stabilization to an external reference source. The applicability of the laser to molecular spectroscopy is demonstrated by detecting CO2 in air using continuous-filtering Vernier spectroscopy.
