For a variety of applications the output power of single-mode laser diodes is not sufficient. Here TOPTICA offers tapered amplifiers in Master Oscillator Power Amplifier (MOPA) configuration as well as stand-alone amplifier systems. Tapered amplifiers feature high powers up to 3.5 W with excellent beam quality and without compromising the favorable spectral qualities of their master lasers. MOPA systems feature TOPTICA's low noise and narrow linewidth master lasers and offer convenient and safe operation with DLC pro.

Serving North America, RPMC Lasers offers optical amplifiers boosting power up to 100 W while retaining your laser’s pulse width, beam divergence, and spectral width. Options include DPSS (1 µm), fiber (1–2 µm), SOA (1.3 & 1.5 µm), and OPA (210 nm – 10 µm, tunable).

Customizable for free-space or fiber-based systems, they deliver configurable power, gain, and pulse options—CW or pulsed down to femtoseconds—in OEM to turnkey formats for seamless integration or lab use.

Built for reliability, these robust amplifiers excel in harsh industrial and aerospace conditions, scaling from research to high-precision needs like spectroscopy and LIDAR with proven durability and performance.

Innolume offers a wide range of semiconductor optical amplifiers (SOAs) for the 780–1310 nm range with a small signal gain of up to 40 dB and a bandwidth of up to 110 nm.

Special types of Innolume’s SOAs, called Booster Optical Amplifiers (BOAs), reach output powers of up to 550 mW and saturation output powers up to 22 dBm.

Our SOAs are equipped with tilted waveguides and anti-reflective coatings to minimize optical feedback, and are available in various packaging options ranging from 14-pin SOA modules to alternative chip placements, including on submounts or as a bare die.

TOPTICA EAGLEYARD offers a variety of tapered amplifiers in different package type. The miniTA is one of the newest innovations.

The miniTA has a fiber-coupled input and collimated output beam and is available in an optimized butterfly package with 14 thicker pins. This hermetically sealed housing is particularly advantageous in industrial applications, as the thicker pins guarantee an ideal supply of power. Furthermore, the forming of the beam, as well as thermal management, are also integrated. Users can enjoy the easy plug-and-play aspect of the fiber plug of the seed laser.

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, optical amplifiers available in pigtailed butterfly packages include InP/InGaAsP or GaAs/InGaAs semiconductor optical amplifiers (BOAs or SOAs). Thorlabs has also developed a family of femtosecond lasers utilizing oscillator-amplifier architectures.

CSRayzer provides several kinds of EDFAs, including multi-channels erbium-doped optical amplifiers, pulsed EDFAs, polarization-maintaining EDFA, with AGC/APC/ACC operation mode. They have a low noise figure and power consumption, high stability and reliability, and can be customized.

MegaWatt Lasers Inc. specializes in producing flash lamp pumped solid-state lasers and pump cavities, which can also be used for amplifiers. Our pump cavities employ the highest reflectivity diffuse reflectors in the industry. We specialize in alexandrite, Nd:YAG, Er:YAG and CTH:YAG gain media. We can provide a wide array of standard laser heads, and can assist in the design of a custom devices for specialized applications.

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.
