Název v původním jazyce

Doped and structured silica optical fibres for fibre laser sources

Popis výsledku v původním jazyce

Specialty optical fibres, usually the silica-based ones doped with rare-earth ions, have been heart of fibre amplifiers and lasers spread thanks to work of team of Sir David N. Payne started in 1980-ies of 20th century. Wavelength of their emission depends on used rare earth, on glass matrix in which the rare earths are incorporated, on fibre structure in macro, micro and nano scale, and fibre laser architecture. Usually, fibre lasers are operated at single wavelength. A typical example is an erbium fibre laser (erbium ions in modified silica glass) operating around 1550 nm or ytterbium fibre laser (ytterbium ions in modified silica glass) operating around 1060 nm. When erbium and ytterbium ions together are randomly distributed in a silica glass matrix and pumped at absorption band of ytterbium, laser emission is typically obtained only at 1550 nm (emission of erbium) thanks to energy transfer from ytterbium to erbium ions, supported by modification of silica glass matrix with phosphorous pentoxide. However, when erbium and ytterbium ions are specifically structured in micro or nano scale in the fibre core it is possible to obtain dual-wavelength laser operation with controlled output parameters. Such dual-wavelength operation with controlled output at 1042 nm and simultaneously at 1550 nm was demonstrated with structured core Er3+ and Yb3+-doped fibre. The proposed approach makes fabrication of active fibres emitting with controlled characteristics at more wavelengths possible.
