| 摘 要： | 介绍了采用国产光纤光栅研制的全光纤激光器，单端泵浦获得468 W的连续激光输出。从理论上分析了光纤光栅的反射率与波长的关系，计算了输出谱宽值，与实验测得的数据相符。全光纤激光器的光-光转换效率达到70%，且随着功率的增加，光纤光栅的中心波长有向长波方向漂移的趋势。在最高输出功率下180 s之内输出功率波动在0.04%以内。

| Abstract: | A high-power all-fiber laser has been designed with a domestic fiber grating as the resonator cavity, and the highest output power of the laser is 468 W. The relationship between the central wavelength of the fiber grating and the output spectral width of the laser is investigated theoretically and experimentally. The experimental optical-optical efficiency can reach 70%, the central wavelength of the fiber grating tends to be larger when the output power increases. The change of the output power in 180 s is less than 0.04% under the highest output power. |
