aeroGAIN-BASE

aeroGAIN-BASE – high power ytterbium fiber gain modules

The aeroGAIN-BASE are high-performance ytterbium fiber gain modules. They are designed for industrial manufacturers of ultrafast pulsed fiber lasers, or you can use them as an easy entry into high-power scientific setups.

We have equipped all modules with an optional 10 or 15 µm step-index single-mode fiber input for easy splicing to a seed source. The gain fiber, our industry-leading DC-200/40-PZ-Yb, has the industry’s largest single-mode MFD.

Key Features

The high pointing stability and low nonlinearity enable a really flexible and versatile laser architecture where the same aeroGAIN-BASE module can be used for amplification of fs-, ps- and ns pulses, with high-frequency conversion efficiency whenever needed.

For optimal performance, the aeroGAIN-BASE modules are designed for counter-propagating pumping through the output end-cap. The end-cap and the last part of the gain fiber are mounted in a water-cooled housing (aeroGAIN-BASE-1.1 and 1.2) to ensure maximum performance and lifetime.

All modules are assembled and tested in cleanrooms. The aeroGAIN-BASE-1.1 and -1.2 come mounted on a tooling plate to ensure the endcap is clean. This tooling plate can also be used as a mount in the laboratory.

The aeroGAIN-BASE design has proven its industrial 24/7 reliability through a significant number of long-term tests including continuous 25,000 hours operation at 55 W output power. Lifetime in specific OEM systems depends on pump power, pump wavelength, cooling efficiency, etc. Get in touch for supporting system design.
