用于EDFA增益锁定的光纤光栅的制作

The Fabrication of Fiber Grating Used in Gain-clamped EDFA

本文报道了基于扫描光束技术 ,采用普通均匀相位模板和连续的 2 44 nm倍频 Ar+ 激光器 ,制作出用于掺铒光纤放大器 (EDFA)增益锁定的光纤光栅。将其置于常规 EDFA中进行测试 ,结果表明制作的光栅能够满足 EDFA增益锁定的要求。

This paper reports a fabrication method of the fiber grating used in gain clamped EDFA based on beam scanning technology and using uniform phase mask and a 244 nm CW frequency doubled Ar+ laser.It shows that this fiber grating satisfies gain clamped requirement of the EDFA.
