中文摘要 | 缠绕技术通常被用于大模场面积多模光纤激光器的横模控制。将光纤弯曲成不同半径的圆环,多模光纤激光器的高阶横模逐个被抑制并在缠绕半径为20mm时,获得15.4W的单模激光输出。实验研究表明,缠绕半径减小时,由于激光器高阶模式被抑制,其光束质量变好,同时其斜率效率降低。实验测量了多模光纤激光器在不同缠绕半径下的输出性能,并理论计算了各阶模式在不同缠绕半径下的损耗特性。实验测量结果与理论计算结果符合得较好。; Coiling technique is used to control the transverse mode of a large-mode-area (LMA) multimode fiber laser. By winding the fiber to a coil with different radius, high-order modes of a multimode fiber laser are suppressed one by one and finally 15.4-W single-transverse-mode output is achieved when the coil radius is 20 mm. It is found that as the coil radius decreases, the beam quality of a multimode fiber laser gets better but the slope efficiency drops for higher-order modes are discriminated. During the experiment, as the coil radius of multimode fiber changes, output characteristic of the laser has been measured. Meanwhile, the mode loss of different modes is calculated theoretically. It is proved that the experimental measured results fit well with the theoretically calculated results. |
