摘要
设计了级联式全光纤1018 nm光源。该光源采用两级级联放大方案,实现了对低功率1018 nm种子光的放大,获得了4.2 W的最大输出功率,并分析了影响放大效率的因素。以获得的1018 nm激光为抽运源,进行了1070 nm信号光的同带抽运放大器实验研究,测量了放大器的输出特性。在纤芯抽运实验中,获得了明显的放大效果和较高的功率转换效率。进行了瓦量级包层同带抽运的实验研究,分析了导致包层抽运实验中功率转换效率偏低的原因并提出了解决方案。
Abstract
Cascaded all-fiber 1018 nm laser source is designed and demonstrated, which can boost the low input 1018 nm signal to 4.2 W. The main factors that have impact on the power conversion efficiency are analyzed. Then the tandem-pumped fiber amplifier is experimentally investigated in which the 1018 nm fiber laser is used as pump source to amplify the 1070 nm signal laser. In the core-pumping experiment, the signal laser is efficiently amplified with a high power conversion efficiency. The reason leading to low power conversion efficiency in cladding-pumped experiment is analyzed and some solutions are proposed.
