At the beginning of 2016, the first direct detection of a gravitational wave by a laser-based
Michelson interferometer has been reported. So far, the number of confirmed detections has …

An optical waveguide amplifier, which can solve the problem of optical attenuation in optical
network transmission, is the key technology to solve optical chip integration and optical …

Optical waveguide amplifiers based on NaYF 4: Er 3+, Yb 3+ nanocrystals prepared by high-
temperature thermal decomposition method with forward and backward pump schemes are …

In this Letter, a high-power Er/Yb-codoped fiber amplifier (EYDFA) with a high-reflection Yb-
band fiber Bragg grating (FBG) at the pump end is experimentally investigated. The FBG …

In this work we demonstrate a single-frequency, single-mode all-fiber master oscillator
power amplifier (MOPA) source, based on erbium–ytterbium co-doped double-clad fiber …

We present a novel technique for all-optical stabilization of the output power of telecom band
amplifiers based on double-clad (DC) erbium-ytterbium (Er: Yb) doped fibers. The proposed …

We report on the design and fabrication of an Er^ 3+: Yb^ 3+ triple clad fiber and on the
power scaling of a single frequency fiber amplifier at 1.5 μm based on that fiber. In addition …

We present effective methods for the numerical simulation of high-power-pumped
continuous-wave (CW) and pulsed erbium–ytterbium-codoped fiber amplifiers (EYDFAs) …

In this paper, Er/Yb co-doped fiber amplifiers (EYDFAs) with an Yb-band fiber Bragg grating
