Abstract Here we propose a simulation model based on a previously reported analytical description of the Brillouin gain, that takes into account pump depletion, which allows us to make very accurate calculations for Brillouin fiber lasers (BFLs) working both in a single and cascaded multi-wavelength configurations. Output powers and conversion efficiencies are analyzed and compared with experimental results for various lasers setups using 25 km of a non-zero dispersion-shifted fiber (NZDSF) as the Brillouin gain media. In our experimental investigations, we used a pump laser at 1565 nm, with a bandwidth of 1 kHz, and output powers varying from 0 to its maximum value of 14 mW. We analyzed the laser behavior under various conditions using output couplers with output ratios varying from 10% to 90%, and to generate the cascaded Brillouin laser we have used a 10 m Erbium-doped optical fiber amplifier as a gain block in a separated cavity. Additionally, a spectral reconstruction is made based on power predictions of our model for the cascaded BFL with excellent agreement with experimental data.

基于分析模型的单波长和级联多波长布里渊光纤激光器仿真解决方案

摘要 在这里，我们提出了一个基于先前报道的布里渊增益分析描述的模拟模型，该模型考虑了泵浦损耗，这使我们能够对在单个和级联多路系统中工作的布里渊光纤激光器 (BFL) 进行非常准确的计算。波长配置。分析输出功率和转换效率，并与使用 25 公里非零色散位移光纤 (NZDSF) 作为布里渊增益介质的各种激光器设置的实验结果进行比较。在我们的实验研究中，我们使用了 1565 nm 的泵浦激光器，带宽为 1 kHz，输出功率从 0 到其最大值 14 mW。我们使用输出比从 10% 到 90% 不等的输出耦合器分析了各种条件下的激光行为，为了产生级联布里渊激光器，我们使用了 10 m 掺铒光纤放大器作为分离腔中的增益块。此外，基于我们的级联 BFL 模型的功率预测进行了光谱重建，与实验数据非常吻合。
