  • Patent number: 10348051
    Abstract: In one embodiment, a fiber-optic amplifier includes an optical gain fiber configured to amplify input light received from a seed laser. The optical gain fiber includes a first gain section configured to: receive the seed-laser input light and co-propagating pump light; and amplify the seed-laser input light as it propagates along the first gain section. The seed-laser input light and the co-propagating pump light propagate along the first gain section in a same direction. The optical gain fiber also includes a second gain section configured to: receive the amplified input light from the first gain section; receive counter-propagating pump light; and further amplify the amplified input light as it propagates along the second gain section. The amplified input light and the counter-propagating pump light propagate along the second gain section in opposite directions. The fiber-optic amplifier also includes a first pump laser diode and a second pump laser diode.
