摘要
作为长距离分布式侧面泵浦技术的典型代表, 泵浦增益一体化复合功能激光光纤(Pump-gain integrated Functional Laser Fiber, PIFL-fiber)是包含单根增益光纤与多根泵浦光纤的多功能集成器件。基于倏逝波耦合效应巧妙地解决了超大泵浦功率注入的技术难题, 已成为高功率光纤激光放大技术的主流技术方案之一。
Abstract
With home-made fiber and multi-fiber combining technique, an (8+1) PIFL fiber was successfully fabricated by Specialty Optical Fibers and Technologies Group (CAEP). Tested in a master oscillator power amplifier (MOPA) laser setup pumped by 976 nm laser diodes with bidirectional-pump method, the fiber presented the maximum laser output of 11.23 kW at 1080 nm. When stabilized at 10.45 kW, the laser setup can work stably for a long time.
