摘　　要：介绍了基于紫外光侧写和相位掩模法制作双包层光纤光栅的工艺,制作了一对中心波长1080 nm的光纤光栅,测试光谱得到其反射谱带宽分别为2 nm和1 nm。采用自制的光纤光栅搭建了一个高功率光纤振荡器,得到最高502 W的激光输出,并测试了输出激光的光谱和光束质量。High power double cladding fiber Bragg grating(FBG) fabrication based on ultraviolet laser and phase mask method was introduced. A pair of chirped FBGs with 1080 nm central wavelength was made. The reflection spectrum bandwidths were 2 nm and 1 nm, respectively. We adopted these FBGs to construct a fiber oscillator. whose output signal power is up to 502 W.
