为了实现一个紧凑和集成的超快光纤激光器系统，我们提出了一个光纤组件作为波分复用器（WDM），输出耦合器（OC），锁模器的磁控溅射饱和吸收体（SA）的实验室锥形耦合器。利用该功能集成耦合器，实现了重复频率112 MHz、脉宽286 fs、信噪比87 dB的掺铒光纤锁模激光器。对锁模激光器的噪声特性进行了表征。据我们所知，这是第一个基于WDM/OC/SA集成器件的锁模光纤激光器的演示。(C)2021光学出版集团
In an effort to realize a compact and integrated ultrafast fiber laser system, we propose a fiber component serving as a wavelength division multiplexer (WDM), output coupler (OC), and mode-locker by a magnetron-sputtering saturable absorber (SA) on a laboratory-tapered coupler. With the function-integrated coupler, an Er-doped mode-locked fiber laser with 112 MHz repetition rate, 286 fs pulse width, and 87 dB signal-to-noise ratio (SNR) is demonstrated. The noise feature of the mode-locked laser is also characterized. To the best of our knowledge, this is the first demonstration of a mode-locked fiber laser based on a WDM/OC/SA integrated device.
