我们测量了空心光子晶体光纤（HC-PCF）气体盒的传输特性与箍和熔融拼接配置，近场和远场图像的HC-PCF的观察。结果表明，远场像的质心随激光频率和温度的变化而变化，运动的质心与振荡传输有关。使用的空间干涉模型，我们首先证明，主要是模式与非对称相位分布影响COM的位置。比较了两种激光器的稳频性能。熔接式气电池的性能优于套管式气电池。
We measure the transmission characteristics of hollow-core photonic crystal fiber (HC-PCF) gas cells with ferrule- and fusion-spliced configurations, and near- and far-field images of the HC-PCF are observed. Results show that the center of mass (COM) of the far-field image varies with the laser frequency and temperature, and the moving COM relates to the oscillatory transmission. Using a model of the spatial interference, we first demonstrate that mainly the modes with asymmetric phase distributions affect the COM position. The frequency stabilization performances of the lasers are compared. The fusion-spliced gas cell shows better performance than the ferrule-spliced one.
