Radiation-Balanced Silica Fiber Amplifier [PDF]

open access: yesPhysical Review Letters, 2021
We report what we believe to be the first radiation-balanced fiber amplifier - a device that provides optical gain while experiencing no temperature rise. The gain medium is a silica fiber with a 21 um-diameter core highly doped with Yb3+ (2.52 wt.%) and co doped with 2.00 wt.% Al to reduce concentration quenching.

51.5 W monolithic single frequency 1.97 $\mathrm {\mu} $m Tm-doped fiber amplifier

open access: yesHigh Power Laser Science and Engineering, 2013
We demonstrate a monolithic single frequency Tm-doped fiber amplifier with output power of 51.5 W. A single frequency fiber laser at 1.97 $\mathrm {\mu} $m is amplified by a cascaded master oscillator power amplifier (MOPA) system with all-fiber ...

Amplifying Orbital Angular Momentum Modes in Ring-Core Erbium-Doped Fiber

open access: yesResearch, 2020
Lots of research efforts have been devoted to increase the transmission capacity in optical communications using orbital angular momentum (OAM) multiplexing. To enable long-haul OAM mode transmission, an in-line OAM fiber amplifier is desired.

Phase conjugate fluorozirconate fibre laser operating at 800nm [PDF]

open access: yes, 1992
We report phase-conjugate feedback into a fluorozirconate optical fiber amplifier at infrared wavelengths. By using a semiconductor laser diode at 807 nm, a grating is established in photorefractive BaTiO3 that, in the ring configuration, provides ...

Theoretical Analysis of Thermal Distribution and Waveform Evolution in Pulsed Ytterbium-Doped Fiber Amplifier with Extra Feedback

open access: yesPhotonics, 2023
Pulsed ytterbium-doped fiber amplifiers (YDFA) with ns-level signal width are important devices for obtaining high-power pulsed lasers. When some components in the amplifier are ineffective, e.g., the isolator or fiber is damaged, extra feedback light is
