【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 d B。
[Abstract]:Because mode-locked fiber laser pulse has the characteristics of high peak power and narrow pulse width, it can be effectively used in high precision remote ranging and information transmission. In this paper, a novel laser output method based on graphene mode-locking is presented, which is based on a fully biasing erbium-doped fiber ring short cavity. The stable output of passive mode-locked pulse sequence can be realized by using multilayer graphene saturable absorber, and the gain and loss of laser at different wavelengths can be effectively controlled by the attenuator actively modulating the loss in the cavity. Experiments show that based on 10 layers graphene saturable absorber, modulation gain balance, the mode-locked pulse sequence laser output at 1 531 nm and 1 557 nm can be realized independently in the short cavity of all polarization-maintaining fiber laser. The repetition rate is about 57 MHz, and the linear polarization can reach 19 dB.
