We report the design of an all-fiber, linearly polarized Yb-doped fiber laser at 1064 nm with a narrow linewidth and high output power required by the master oscillator of the amplifier for high-power spectral beam combining. The laser has achieved linearly polarized output with a polarization extinction ratio of 23 dB, a narrow linewidth of ≤52 pm, and an output power of 32.7 W. Such performance was obtained by the cavity design that incorporated a wavelength-shifted PM fiber Bragg grating pair and single-mode-multimode-single-mode structure.
我们报道了一种全光纤线性偏振掺镱光纤激光器的设计，该激光器工作在1064 nm波长，具有窄线宽和高输出功率，这是高功率光谱合束放大器主振荡器所要求的。该激光器实现了线性偏振输出，偏振消光比为23 dB，窄线宽≤52 pm，输出功率为32.7 W。通过采用包含波长偏移保偏光纤布拉格光栅对和单模-多模-单模结构的腔设计获得了这样的性能。
