Where to Buy Fiber Amplifiers

Thorlabs manufactures erbium (Er)-, ytterbium (Yb)-, and praseodymium (Pr)-doped fiber amplifiers for applications from ultrafast pulse amplification to datacom. Along with these stand-alone benchtop amplifiers, Thorlabs has developed a family of femtosecond lasers utilizing oscillator-amplifier architectures.

Based on Cycle's own femtosecond fiber lasers, the company also offers fiber-based amplifiers (EDFA) with a center wavelength of 1550 nm to 1700 nm. This variant of the SOPRANO-15 is a very attractive solution to amplify the output of beam arrival monitors in synchrotron or FEL facilities, for example. Other custom-made fiber amplifiers are available upon request.

AdValue Photonics offers fiber amplifiers for wavelength around 1 μm, 1.5 μm or 2 μm. They are suitable for pulsed or continuous-operation, narrow linewidth or broadband light.

For the 1-μm region, we have compact and yet powerful large mode area fiber amplifier modules, which can deliver more than 120 W average output power.

AFS’s customized kW average power and multi-mJ pulse energy ultrafast laser systems are based on AFS leading-edge fiber technology. They unite multiple main-amplifier channels using coherent combination, a technology which AFS has matured to an industrial grade. All essential parameters are software-controlled and can be tuned over a wide range, making them an extremely valuable tool for numerous application.

Lumibird manufactures an extensive range of mature and custom-designed optical fiber amplifiers and fiber lasers. High output powers are achieved through the use of double cladding fibers pumped by broad stripe diodes. Several varieties of pumping techniques are used each optimized for specific applications. Lumibird also develops key components for producing unique and innovative light sources.

In 1995, MPB Communications provided its first generation of high-power boosters and quantum-limited noise-figure EDFAs for long-haul, unrepeatered telecom systems. MPBC amplification solutions have been adopted by system integrators in the terrestrial, submarine and utilities markets and continue to offer exceptional reliability which power communication backbones worldwide.

Today, our fiber amplifier technology can be found in our line of network-ready telecom solutions, as well as in our extensive portfolio of gain modules, and in our single-frequency Raman fiber amplifiers.

RPMC offers a wide range of Telcordia grade erbium and ytterbium fiber lasers and amplifiers that are deployed in a wide range of applications, including LIDAR, mapping, 3D scanning and telecommunications. The BKtel suite of lasers and amplifiers are available in a range of wavelengths from 1030 nm to 2050 nm, with average powers up to 100 W, pulsed and CW capabilities, and numerous features, including low noise, compact package size, and a digital control system.

LaserNGN is a counter-pumping amplification module based on INO’s Yb-doped tapered PM optical fiber technology. It provides excellent output mode quality (M² < 1.3) and reliable operation at high peak power and high average power thanks to INO low-photodarkening core chemistry. LaserNGN can be operated TMI-free at up to 100 W of average output power without affecting beam quality and polarization. The module can be easily integrated with a pigtailed oscillator using its standard 10/125 PM input fiber. For further ease of operation, we also offer an optional pre-aligned pump-injection module specifically designed for the LaserNGN gain module.

Thanks to their high rare-earth solubility (up to 100,000 ppm) and low phonon energy, LVF fluoride fibers offer dozens of active transitions, enabling a broad range of applications from visible to the mid-infrared, one of which is amplification. For example, LVF praseodymium and thulium doped fibers are used for amplification at 1.3 µm and 1.47 µm respectively. LVF doped fibers for amplification are available as single-mode fiber or double cladding fiber.

Le Verre Fluoré will soon offer laser and amplifier fiber modules. The required fiber will be integrated in a robust housing and connectorized with FC/PC, FC/APC, SMA or custom connectors depending on customer need: this is a plug-and-play module.

Depending on specific needs, modules might include single-mode or multimode splices between fluoride fibers or between silica and fluoride fibers.

DK Photonics offers various erbium-doped fiber amplifiers for telecom applications, including compact amplifier modules as well as bench-top instruments with controls and displays.

Ytterbium-doped amplifiers for the 1-μm wavelength region are also available.
