摘要
当前光纤激光功率提升受限于模式不稳定效应及非线性效应,为了克服上述功率提升限制因素,自主设计并研制了大模场部分掺杂光纤。最终,采用自研部分掺杂光纤及后向级联泵浦方案,成功实现了10.1 kW的光纤激光输出,对应的光束质量因子(M2)为2.16。
Power scaling of high-brightness fiber laser is limited by the mode instability and nonlinear effects.To overcome these limiting factors,a large mode area confined-doped fiber is designed and fabricated.By utilizing the homemade confined-doped fiber and backward tandem pumping scheme,fiber laser with output power of 10.1 kW is successfully achieved,where the corresponding beam quality factor(M2)is 2.16.
