Multimode Mamyshev Oscillator
Henry Haig, Pavel Sidorenko, Anirban Dhar +4
We present a spatiotemporally mode-locked Mamyshev oscillator. A wide variety of multimode mode-locked states, with varying degrees of spatiotemporal coupling, are observed. We fin…
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…
Preparation and Properties of Er-Doped ZrO2 Nanocrystalline Phase-Separated Preforms of Optical Fibers by MCVD Process
Anirban Dhar, Ivan Kasik, Ondrej Podrazky +2
The fabrication of Er-doped ZrO2-based nanocrystalline phase-separated silica optical preforms by the MCVD and solution doping techniques is presented. Fabricated preform cores are…
