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…
High harmonic generation in monolayer MoS2 controlled by resonant and near-resonant pulses on ultrashort time scales
Pavel Peterka, Artur O. Slobodeniuk, Tomáš Novotný +5
We report on experimental investigation of nonperturbative high harmonic generation (HHG) in monolayer MoS2 in the ultraviolet spectral region driven by mid-infrared light. We stud…
Noncollinear phase-matching of high harmonic generation in solids
Pavel Peterka, František Trojánek, Petr Malý +1
We propose and experimentally demonstrate a scheme allowing to reach noncollinear phase-matching of high harmonic generation in solids, which may potentially lead to an enhancement…
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…
