Structured Ytterbium and Erbium -doped Silica Fiber for Dual Wavelength Laser Operation
Ivo Barton, Pavel Peterka, Martin Grabner +9
We report on a novel type of dual-wavelength fiber laser with a structured-core design inside silica glass, forming a spatial separation of the several core areas doped with ytterb…
Doped and structured silica optical fibres for fibre laser sources
I. Kasik, I. Barton, M. Kamradek +8
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. Pay…
Nanoparticle doping as a way to enhance holmium fiber lasers efficiency
M. Kamradek, I. Kasik, J. Aubrecht +6
Highly-doped holmium fibers have been prepared using modified chemical vapor deposition in combination with nanoparticle-doping method. Within a series of various Al2O3 and Ho3+ co…
Preparation and characterization of highly thulium- and alumina-doped optical fibers for single-frequency fiber lasers
Pavel Honzatko, Anirban Dhar, Ivan Kasik +5
Thulium-doped fibers suitable for core-pumped single-frequency lasers were fabricated by the modified chemical vapor deposition (MCVD) method. Refractive index profile, doping prof…
Thulium-doped silica fibers with enhanced 3H4 level lifetime: modelling the devices for 800-820 nm band
Pavel Peterka, Ivan Kasik, Anirban Dhar +2
Silica-based thulium-doped fiber devices operating around 810 nm would extend the spectral range covered by high- power fiber devices. Using a comprehensive numerical model of the…
