Single-mode Er:Yb fiber solutions for power scaling in next-generation 1.5µm fiber laser systems

This work introduces Exail’s latest erbium/ytterbium co-doped optical fiber, designed to push the limits of single-mode fiber lasers operating at 1.5 µm — a key wavelength for applications such as free-space optical communications, LiDAR and hashtag#quantum technologies.

Power efficient all-fiberized 12-core erbium/ytterbium doped optical amplifier

20dB gain in C-band with only 5.3W of pump is achieved with an all-fiberized 12-core Er/Yb doped fiber amplifier. This result is a first step towards SDM transmission including power efficient amplifiers and ROADM.

High Peak Power Single-Frequency Amplifier based on a Er-Yb Doped Polarization Maintaining LMA Fiber

We report on single-frequency all-fiber amplifiers based on PM Er-Yb doped P2O5-Al2O3-SiO2 fibers. Peak power up to 700W at 1545nm for 730ns pulse duration has been obtained with a good beam quality and a 17dB PER was measured.

Ixnews 2018 photonics west special issue: erbium-ytterbium doped optical fibers

When iXFiber was created in 2006, most of the team had some experience with Erbium-Ytterbium co-doped double clad fibers

High peak power single-frequency mopfa for lidar applications

Long range coherent detection wind lidars have many applications in the fields of wind farms and aircraft safety. Fiber laser sources emitting around 1.5 µm show key advantages such as versatility, modularity and obustness of alignments to vibrations. However, nonlinear effects such as Stimulated-Brillouin-Scattering limit achievable peak power because of strong fiber core confinement.

High peak power single-frequency efficient erbium-ytterbium doped LMA fiber

We report on single-frequency all-fiber amplifiers based on Er-Yb doped P2O5-Al2O3- SiO2 fibers. Peak power up to 1120 W at 1545 nm for 108 ns pulse duration has been obtained with 18 % slope-efficiency. Continuous-wave operation generated up to 14 W.
