Nanocrystals could extend fibre laser wavelength coverage
The fibre laser is a compact, energy-efficient alternative to the standard solid-state laser. It has set a strong track record for high-power, high-quality laser beams. Most fibre lasers are fabricated from durable silica glass. Their operation could be extended to other spectral regions by doping them with nanocrystals optimised for particular wavelengths. The EU-funded NCLas project plans to develop a disruptive technology for synthesising glasses containing functional nanocrystals. The technology will be based on a novel hybrid sintering process that allows incorporating a large variety of nanocrystals and functionalising glasses in different formats for various applications. To match the refractive indices of nanocrystals and glass, researchers will use lower than usual temperatures, develop specialised nanocrystal core-shell structures and adjust glass composition.
