Choosing the right doped fiber takes more than a wavelength
The right gain fiber depends on much more than the target emission wavelength. Power level, pump configuration, core and cladding architecture, polarization requirements and operating environment all influence fiber selection.
That's where Exail's expertise makes the difference.
From standard fibers to customized designs, our specialists help you identify the right solution for your system and application. We manufacture and characterize our fibers in-house, allowing us to control the process from fiber design to performance measurement.
This approach allows us to provide guidance tailored to your technical requirements and application.
Which DOPED FIBER fits your application?
From wavelength and power to operating environment, compare our main doped fiber technologies below.
 | Typical wavelength | Power* | Environment | Applications |
|---|---|---|---|---|
Ytterbium | ~1 µm | Low → High | Industrial, harsh environments | High-power lasers, LIDAR |
Erbium | ~1.5 µm | Low → High | Telecom, space | Optical amplifiers, communications |
Erbium/Ytterbium | ~1.5 µm | Medium → High | Industrial, space | High-power lasers, LIDAR, communications |
Thulium | ~2 µm | Medium → High | Industrial, medical, defense | 2 µm lasers, LIDAR |
Holmium | ~2 µm | Medium → High | Harsh environments | 2 µm lasers, LIDAR, defense |
Thulium/Holmium | ~2 µm | Medium → High | Demanding environments | High-power 2 µm lasers |
Neodymium | ~0.9–1.1 µm | Medium → High | Industrial, laboratory | Lasers & amplifiers |
*Actual power capability depends on fiber architecture and system configuration.
