Abstract

We propose and experimentally demonstrate a stable high-order mode (HOM) Brillouin random fiber laser based on randomly distributed Rayleigh scattering in few-mode fibers. Taking advantage of a few-mode erbium-doped fiber-based dynamic fiber grating with self-matched spatial mode, mode hopping of HOM Stokes random laser can be significantly suppressed, benefiting prominent intensity noise reduction and laser frequency stabilization. Results show that, the power fluctuation of the proposed laser with few-mode dynamic fiber grating is reduced by 50%, while the variance of the laser frequency fluctuations within 1000 milliseconds has been optimized down to 0.15. Notably, the LP11 mode of the laser output achieves a purity exceeding 95% with fluctuations reduced by 56.9%. It is believed that the proposed HOM laser would be promising for applications in optical fiber communication and fiber sensing.

利用自匹配动态光纤光栅稳定高阶模布里渊随机光纤激光器

本文提出并实验证明了一种基于少模光纤中随机分布瑞利散射的稳定高阶模布里渊随机光纤激光器。利用基于掺铒光纤的空间模式自匹配的动态光纤光栅，可以显著抑制HOM Stokes随机激光器的模式跳变，有利于显著的强度降噪和激光稳频。结果表明，采用少模动态光纤光栅的激光器的功率波动减小了50%，而在1000毫秒内的激光频率波动方差优化到0.15。值得注意的是，激光输出的LP11模式纯度超过95%，波动降低了56.9%。该激光器在光纤通信和光纤传感领域具有广阔的应用前景。
