Proceedings ArticleDOI
On the Pulse Fidelity in Monolithic Single Mode Femtosecond Ytterbium Fiber Amplifiers
Aart J. Verhoef,L. Zhu,Tobias Flöry,Kim G. Jespersen,Lars Gruner-Nielsen,Almantas Galvanauskas,Andrius Baltuška,Alma Fernandez +7 more
TL;DR: In this paper, the first nonlinear phase characterization of a monolithic single mode fiber amplifier with a dispersion compensating fiber stretcher was presented, yielding high fidelity sub-200 fs pulses.
Proceedings ArticleDOI
Versatile Yb-fiber-amplifier-based CEP-stable front-end for OPCPA
Alma Fernandez,L. Zhu,Aart J. Verhoef,Dmitry A. Sidorov-Biryukov,Chi Hung Liu,Kai-Hsiu Liao,Almantas Galvanauskas,S. Kane,Audrius Pugzlys,Andrius Baltuška +9 more
TL;DR: In this paper, the authors demonstrate a drastically simplified seeding/synchronization approach based on an environmentally stable µJ-energy 200-fs 100-kHz Yb-doped fiber amplifier (YDFA) that generates a white light continuum in bulk sapphire, pumps a DFG OPA and provides an optical seed compatible with most Nd and Yb ∼1-µm pump pulse amplifiers.
Proceedings ArticleDOI
Mirrorless Backward SRS in Free-Space Gas Driven by Filament-Initiated UV Laser
Pavel Malevich,Raffael Maurer,Daniil Kartashov,Skirmantas Alisauskas,Marco Marangoni,Giulio Cerullo,Aleksei M. Zheltikov,Audrius Pugžlys,Andrius Baltuška +8 more
TL;DR: Stimulated Raman scattering combined with ASE lasing from nitrogen molecules in a femtosecond filament is shown to provide a highly directional chemical-bond-sensitive coherent readout in the direction opposite to that of the driver laser beams as mentioned in this paper.
Proceedings ArticleDOI
Controlling molecular isomerization and fragmentation with laser-induced electron recollision
Xinhua Xie,Katharina Doblhoff-Dier,Stefan Roither,Markus Schöffler,Daniil Kartashov,Huailiang Xu,Tim Rathje,Gerhard G. Paulus,Andrius Baltuška,Stefanie Gräfe,Markus Kitzler +10 more
TL;DR: In this article, the authors present the first, to the best of our knowledge, CEP control of fragmentation pathways of polyatomic molecules (acetylene, ethylene, 1,3-butadiene) given the increased number of participating nuclei and a vastly more complex valence electron dynamics and the structure of energy surfaces.
Proceedings ArticleDOI
Material Processing with Picosecond 2-μm Pulses from Ho:YAG Amplifier
TL;DR: In this paper, a robust 2.09-μm, 3.2-ps, 1.6-mJ, 16-W Ho:YAG CPA system with a simple dispersion and bandwidth management is developed and employed for material processing.
