| 摘 要： | 报道了一种基于石墨烯锁模的全保偏掺铒光纤环形短腔实现锁模激光波长切换技术。利用多层石墨烯可饱和吸收镜不仅可实现被动锁模脉冲序列的稳定输出,并可通过三维精密调节,调制腔内信号损耗,有效控制不同波长激光的增益与损耗。实验表明,通过精密调制10层石墨烯膜可饱和吸收镜,在全保偏光纤激光短腔可实现波长1532 nm和1558 nm 处的锁模激光切换输出,并可实现这两波长附近的双波长锁模激光输出,线偏振度可达18 dB。

| Abstract: | Wavelength switching of all-polarization-maintaining Er-doped mode-locked fiber laser based on graphene saturable absorber is reported.Based on multi-layer graphene saturable absorber mirror,stable mode-locked fiber laser can be obtained,and cavity loss can be modulated by tuning the mirror in three-dimensional orientation,which can control the gain and loss of laser with different wavelengths.The experimental results show that wavelength switching at center of 1532 nm and 1560 nm can be realized by adjusting graphene saturable absorber mirror,and dual-wavelength mode-locked laser can be obtained in short cavity.Extinction ratio of output laser can be up to 18 dB. |
