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…
7-Rod-Core Thulium-Doped Fiber for Enhanced Fiber Laser Cooling
Ivo BartoÅ, Jan Aubrecht, Bara Å vejkarová +7
Structured-core thulium-doped fibers were developed to reduce heat load, enable shorter-wavelength operation, and achieve a pedestal-free design. In a proof-of-principle experiment…
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…
