EDFA Technology

Erbium-doped fibre amplifiers, tailored end-to-end to your application.

Our EDFAs

We build EDFAs for any application — LiDAR, quantum, free-space comms, sensing, and beyond. Each one scoped and built to your requirements.

Every parameter is configurable — we push power as far as it goes commercially with pulse energies above 10 mJ, peak powers above 100 kW, and average powers above 100 W.

Just let us know your spec.

The parameters above are set in stone — everything else is configurable:

Operating band — C-band (1530–1565 nm), L-band (1565–1625 nm), or dual C+L from a single source via a single delivery cable
Output power
Pulse regime (CW, short-pulse, or custom)
Pulse energy and peak power
Cooling (air or water, depending on power class)
Delivery cable length and termination
Form factor and integration envelope
Control firmware and interface: USB, RS232, Parallel I/O (for Scan Controllers)
Beacon / direction (see Free Space Optical Communications)

Power is fully customisable to your application. At the top of our range, WSL builds the highest-power erbium-doped fibre lasers commercially available — pulse energies above 10 mJ, peak powers above 100 kW, and average powers above 100 W.

Yes. WSL can configure a single laser source to provide both C-band and L-band output through a single long delivery cable — simplifying integration in complex optical ground stations.

Depends on configuration and integration requirements. Typical engagements start with a scoping conversation - booking a call with our team is the fastest route.

Yes. Control behaviour, communication standards, and operating modes are software-definable.

1550 nm sits in the eye-safe C-band — the cornea and lens absorb the wavelength before it reaches the retina, dramatically raising the maximum permissible exposure compared to 1 μm sources.

Yes. WSL provides direct engineering support throughout integration.

Globally. Our technology is built in Southampton (UK) and supplied to integrators and programmes worldwide.
