我们展示了一个掺镱光纤激光器，有效地发射高功率径向偏振光。采用光子晶体光栅（PCG）作为偏振选择输出耦合器，输出的径向偏振激光功率达到2.42 W，斜率效率为45.9%，偏振纯度为96%。结果表明，在光纤激光器中加入PCG反射镜可以有效地产生高功率径向偏振光，具有重要的应用前景。
We demonstrate an ytterbium-doped fiber laser that emits high-power radially polarized light efficiently. In this study, a photonic crystal grating (PCG) was used as a polarization-selective output coupler, and the power of the radially polarized laser reached 2.42 W with a slope efficiency of 45.9% and a polarization purity of 96%. The results reveal that the inclusion of the PCG mirror into the fiber laser are particularly promising for generating high-power radially polarized light efficiently in view of its many important applications.
