| 摘 要： | 提出了一种在2050 nm波段的基于新型无源三环复合子腔的单纵模掺铥光纤激光器。对所提出的新型复合三环子腔滤波器进行了详细的理论分析,可以通过调整其有效自由光谱范围和透射带宽实现超窄带滤波,从而确保激光器的单纵模运行。所搭建激光器的输出波长为2048.48 nm,光信噪比为70 dB,100 min内的波长和功率波动分别小于0.02 nm和0.453 dB。实验结果表明,激光器可以工作在稳定的单纵模输出状态。该激光器有望用于自由空间光通信或用作多普勒激光雷达的高功率光纤激光器的种子源。 |

| Abstract: | A single-longitudinal-mode(SLM)thulium-doped fiber laser in 2050 nm band enabled by a novel passive triple-ring compound cavity filter was proposed and demonstrated.Theoretically analyzing of this sub-cavity filter was performed in detail.The use of the compound cavity filter in the fiber laser guaranteed the SLM lasing by carefully adjusting the effective free spectral range and transmission bandwidth for ultra-narrow filtering.The output wavelength of the fiber laser was 2048.48 nm,and the optical signal-to-noise ratio was 70 dB.The wavelength and power fluctuations measured within 100 min were less than 0.02 nm and 0.453 dB,respectively.Experimental results verified that the fiber laser could operate in a stable SLM lasing state.The proposed laser is promising to be used in free-space optical communication or be used as the seed source of the high power fiber laser for Doppler Lidar. |
