报道了一种基于石墨烯可饱和吸收体（SA）和非平衡马赫-曾德尔干涉仪（UMZI）的全光纤调Q掺铒光纤激光器（EDFL）。调Q激光器的波长可以在~35 nm的范围内精确调谐，通过在一个臂中插入具有可变光学延迟线（OVDL）的UMZI，其充当进入腔中的光束滤波器。对调Q脉冲宽度和脉冲能量进行了表征。最大脉冲能量为36.9nJ。
An all fiber, wavelength tunable, Q-switched erbium-doped fiber laser (EDFL) based on a graphene saturable absorber (SA) and an unbalanced Mach–Zehnder interferometer (UMZI) has been demonstrated. The wavelengths of the Q-switched laser can be accurately tuned over a range of ~35 nm by inserting into the cavity an UMZI with a variable optical delay line (OVDL) in one arm, which acts as an optical beam filter into the cavity. The Q-switched pulse duration and the pulse energy have all been characterized. The maximum pulse energy of 36.9 nJ was obtained.
