Journal ArticleDOI
Millijoule pulse energy high repetition rate femtosecond fiber chirped-pulse amplification system
Fabian Röser,Tino Eidam,Jan Rothhardt,Oliver Schmidt,Damian N. Schimpf,Jens Limpert,Andreas Tünnermann +6 more
TL;DR: To the knowledge, this work presents the highest pulse energy ever extracted from fiber based femtosecond laser systems, and a nearly 2 orders of magnitude higher repetition rate than in previously published millijoule-level fiber CPA systems.
Journal ArticleDOI
Supercontinuum generation by femtosecond single and dual wavelength pumping in photonic crystal fibers with two zero dispersion wavelengths
TL;DR: Details about the expansion of the blue but also the red side of the continuum due to cross-phase modulation (XPM) and transfer of energy to dispersive waves are revealed and experimentally confirmed.
Journal ArticleDOI
Efficient high-power generation of visible and mid-infrared light by degenerate four-wave-mixing in a large-mode-area photonic-crystal fiber
TL;DR: An efficient and simple approach for converting pulsed near-IR laser radiation into visible and mid-IR light by exploiting degenerate four-wave-mixing in an endlessly single-mode, large-mode-area photonic-crystal fiber is presented.
Journal ArticleDOI
Compensation of pulse-distortion in saturated laser amplifiers
TL;DR: An expression describing pre-compensation of pulse-distortion due to saturation effects in short pulse laser-amplifiers is derived and will prove useful in applications of high power, high energy laser-AMplifier systems that need particular pulse-shapes to be efficient, e.g. micromachining and scientific laser-matter-interactions.
Journal ArticleDOI
High Repetition Rate Gigawatt Peak Power Fiber Laser Systems: Challenges, Design, and Experiment
Jens Limpert,Fabian Röser,Damian N. Schimpf,Enrico Seise,Tino Eidam,Steffen Hädrich,Jan Rothhardt,César Jauregui Misas,Andreas Tünnermann +8 more
TL;DR: In this paper, the authors present a detailed analysis and optimization of the extraction characteristics in connection with the accumulated nonlinear phase in such extreme fiber dimensions, and show that low-NL rare-earth-doped fibers are the key element for successful peak power scaling in fiber laser systems.
