What is Neodymium?
Neodymium is a rare-earth element that can be used as a dopant in optical fibers to provide optical gain for laser generation and amplification. Neodymium-doped fiber sources can operate around the 900–1,000 nm wavelength range, making them particularly relevant to applications requiring near-infrared laser emission.
Neodymium-doped fibers can provide a compact, efficient alternative to bulk laser architectures. Their properties are also relevant to emerging biomedical imaging techniques, including multi-photon microscopy, where wavelengths around 920 nm are used for two-photon excitation.
key properties of Neodymium
Near-infrared emission
Neodymium can provide laser emission in the near-infrared region, including around 900–1,000 nm depending on the fiber design and transition used.
Efficient fiber gain
When incorporated into a suitable glass matrix, neodymium ions can absorb pump energy and provide optical gain through stimulated emission.
Suitable for pulsed sources
Neodymium-doped fiber architectures can support pulsed laser operation, making them useful for applications requiring high peak power and short optical pulses.
