论文摘要
本文介绍了一种基于增强的偏振损失(PDL)的模式锁定技术。该方法利用弯曲的单模纤维(SMF28)线圈在2 \(μ\)M波长区域诱导足够的PDL。启用了SMF28线圈中的显着PDL,因为光的引导性较弱。使用具有极化控制器作为模式储物柜的简单设备,可以证明一种被动模式锁定的Thulium掺杂的全纤维激光器。结果表明,中等量的1 dB足以启动和维持稳定的模式锁定操作。我们认为,据我们所知,这是基于弯曲纤维部分的偏振属性的模式锁定光纤激光器的首次演示。
This paper describes a mode locking technique based on enhanced polarization dependent loss (PDL). The method utilizes a bent single mode fiber (SMF28) coil to induce sufficient PDL at 2 \(μ\)m wavelength region. Significant PDL in SMF28 coils is enabled since the light is much more weakly guided. A passively mode-locked thulium doped all-fiber laser is demonstrated using this simple device with polarization controllers as mode locker. The results indicate a moderate amount of 1 dB is sufficient to initiate and sustain stable mode-locking operation. We believe, to the best of our knowledge, this is the first demonstration of mode-locked fiber laser fully based on polarization dependent property of bent fiber section.
