弯曲的多模掺Yb^(3+)双包层光纤激光器基模输出研究

Single Transverse Mode Operation from a Coiled Multimode Yb^(3+) Doped Double Clad Fiber Laser

将一段纤芯直径为28.6μm,数值孔径为0.10的掺Yb3+双包层光纤弯曲后可以得到基模激光输出,其输出最大功率为0.35W,中心波长为1073nm。实验结果和理论分析结果基本一致。

By coiling a section of Yb^3＋ double clad fiber laser with the core diameter of 26.8 μm and the numerical aperture of 0.10,the laser of single transverse mode can be obtained. In the experiment, the laser of output power 0.35W and central wavelength of 1073nm is yielded. The theoretical analysis agrees with the experimental results basicaUy.
