| 中文摘要: |
| 因为锁模光纤激光脉冲具有峰值功率高，脉宽窄等特点，可有效应用于高精密远程测距及信息传输等方面。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双锁模脉冲序列激光输出方法。利用多层石墨烯可饱和吸收镜可实现被动锁模脉冲序列的稳定输出，并通过衰减器主动调制腔内损耗，可有效控制不同波长处激光的增益与损耗。实验表明，基于10层石墨烯可饱和吸收镜，调制增益平衡，在全保偏光纤激光短腔内可分别独立实现波长1 531和1 557 nm处的锁模脉冲序列激光输出，重复频率约57 MHz，线偏振度可达19 dB。 |

| Mode locked fiber laser has the properties of high peak power and narrow pulse width, and can be effectively applied in high accurate remote ranging and information transmission. In the paper, a method of realizing dual pulse train mode locked laser in an all polarization maintaining Er doped fiber cavity 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 operated by modulating an attenuator in the cavity. By adjusting the gain and loss of laser signal at different wavelength, dual pulse train laser centered at 1 531 nm and 1 557 nm can be realized, repetition frequency 57 MHz and extinction ratio of output laser can be up to 19 dB. |
