摘要

我们制备了两个波长范围为1074 - 1100 nm的光纤布拉格光栅(FBG)阵列，光谱宽度均为0.1 nm，反射率约为单个光栅的1%，以便研究由声光调制器调q，重复频率为2.6 kHz的Yb光纤激光器发出的脉冲。利用fbg阵列观察了光纤激光谐振腔中若干往返高尖峰的发展，并对其进行了光谱分析。

Investigation of fiber laser pulses by a fiber-Bragg-grating (FBG) spectrum analyzer

We prepared two fiber-Bragg-gratings (FBG)-arrays for the wavelength range 1074 - 1100 nm, both with a spectral width of 0.1 nm and a reflectivity of about 1% of the individual gratings so that pulses are investigated from an Yb fiber laser, Q-switched by an acousto-optical modulator with a repetition rate of 2.6 kHz. Using FBG-array the development of high spikes over some roundtrips in the fiber laser resonator was observed and spectrally analyzed.
