光纤放大器中原子介质的折射率变化

Changing of the Index of the Atom Medium on Fiber Amplifer

本文用三能级原子模型描述双频场中光纤放大器的原子介质,讨论介质对弱探测场透明以及折射率变化。

In this paper, the atom medium on hybrid pumped fiber amplifer was described by a three--level atomic system. We discuss that laser field can lead to the transparency of the medium to the weak probe field and the medium can generate a large refractive index.
