载氢光纤在255．3nm激光辐照下的光折变效应

Photorefractivity in Hydrogen Loaded Fibers at 255.3 nm UV Light Radiation

首次报道采用铜蒸气倍频２５５．３ｎｍ紫外激光辐照载氢光纤产生的光折变效应。

The 255.3 nm light of a frequency doubled copper vapor laser is used to study the photorefractivity of hydrogen loaded fibers for the first time. The measured refractive index change is found to be large enough to make practical gratings in the fibers.
