Jaroslaw Sotor,Maria Pawliszewska,Grzegorz Sobon,Pawel Kaczmarek,Aleksandra Przewolka,Iwona Pasternak,Jakub Cajzl,Pavel Peterka,Pavel Honzatko,Ivan Kašík,Wlodek Strupinski,Krzysztof M. Abramski +11 more
TL;DR: A graphene mode-locked, all-fiber Ho-doped fiber laser generating 1.3 nJ energy pulses directly from the oscillator and the influence of the output coupling ratio and the SA modulation depth on the mode-locking performance was investigated.
Journal ArticleDOI
Nanoparticle and Solution Doping for Efficient Holmium Fiber Lasers
Michal Kamrádek,Pavel Honzatko,Ivan Kašík,Jan Aubrecht,Jan Mrázek,Ondrej Podrazky,Jakub Cajzl,Petr Varak,Václav Kubeček,Pavel Peterka +9 more
TL;DR: In this paper, a set of 15 fibers with various compositions was characterized and compared with respect to their fluorescence lifetime, laser slope efficiency and laser threshold, and the best performance fibers exhibited slope efficiency 83.1%, laser threshold 155 mW and a record value of upper laser level lifetime of 1.35 ms.
Journal ArticleDOI
Thulium-Doped Silica Fibers with Enhanced Fluorescence Lifetime and Their Application in Ultrafast Fiber Lasers
Jakub Cajzl,Pavel Peterka,Maciej Kowalczyk,Jan Tarka,Grzegorz Sobon,Jaroslaw Sotor,Jan Aubrecht,Pavel Honzatko,Ivan Kašík +8 more
TL;DR: In this paper, the authors report on the thulium-doped silica-based optical fibers with increased fluorescence lifetime of the 3F4 level thanks to the modification of the local environment of Tm3+ ions by high content of alumina.
Journal ArticleDOI
Active Optical Fibers and Components for Fiber Lasers Emitting in the 2-μm Spectral Range.
Filip Todorov,Jan Aubrecht,Pavel Peterka,Ondřej Schreiber,Ondřej Schreiber,Ali Abdulhadi Jasim,Jan Mrázek,Ondřej Podrazký,Michal Kamrádek,Nithyanandan Kanagaraj,Nithyanandan Kanagaraj,Martin Grábner,Yauhen Baravets,Jakub Cajzl,Pavel Koška,Adam Fišar,Ivan Kašík,Pavel Honzatko +17 more
TL;DR: The first results of improvement of pump absorption in double-clad fibers thanks to the fiber twist frozen during drawing are presented and a brief demonstration of material processing by thulium all-fiber laser operating at 2 µm is presented.
Journal ArticleDOI
Erbium and Al2O3 nanocrystals-doped silica optical fibers
Ivan Kašík,O. Podrazky,Jan Mrázek,Jakub Cajzl,Jan Aubrecht,Jana Proboštová,Pavel Peterka,Pavel Honzatko,Anirban Dhar +8 more
TL;DR: In this article, the authors deal with the preparation of silica fibers doped with erbium and Al2O3 nanocrystals and the characterization of their optical properties, and the fibers were prepared by the extended Modified Chemical Vapor Deposition (MCVD) method from starting chlorides or oxide nanopowders.
