Active Rare-Earth Doped Fibers: Enabling High-Power Fiber Lasers and Amplifiers
Active rare-earth doped fibers are crucial components in fiber lasers and amplifiers, enabling efficient light amplification through stimulated emission. These fibers are doped with rare-earth ions such as erbium (Er), ytterbium (Yb), or neodymium (Nd), which serve as gain media when pumped with appropriate light sources.
FindLight provides a variety of rare-earth doped fibers designed for different wavelength regimes and power levels. These fibers are widely used in telecommunications for optical amplification, in industrial laser systems for cutting and welding, and in medical applications for precise laser treatments.
The design of active doped fibers considers factors such as doping concentration, core and cladding geometry, pump absorption efficiency, and compatibility with pump diodes. Proper fiber design ensures high gain, low noise, excellent beam quality, and efficient thermal management.
FindLight’s catalog features fibers optimized for continuous-wave and pulsed laser operation, supporting diverse applications from high-power industrial lasers to compact medical devices. The availability of specialty fibers enables system integrators and researchers to develop customized laser solutions.
Selecting the right doped fiber involves evaluating the pump wavelength, absorption characteristics, emission bandwidth, and mechanical robustness. Active fibers from FindLight ensure superior performance and reliability for advanced photonic systems.
