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。
In this paper, we report the fabrication of a fiber grating for gain locking of erbium doped fiber amplifier (EDFA) based on the scanning beam technique using an ordinary uniform phase mask and a continuous 2 44 nm frequency doubling Ar + laser. Put it in the regular EDFA for testing, the results show that the grating can be prepared to meet the EDFA gain lock requirements.
