TL;DR: In this paper, a photonic-crystal fiber filled with krypton gas has been used to realize an extreme-ultraviolet source with a megahertz repetition rate, achieving both high photon flux and high repetition rate simultaneously.
High-repetition-rate and high-photon-flux 70 eV high-harmonic source for coincidence ion imaging of gas-phase molecules
Jan Rothhardt,Steffen Hädrich,Yariv Shamir,Maxim Tschnernajew,Robert Klas,Armin Hoffmann,Getnet K. Tadesse,Arno Klenke,Thomas Gottschall,Tino Eidam,Jens Limpert,Andreas Tünnermann,Rebecca Boll,Cédric Bomme,Hatem Dachraoui,Benjamin Erk,Michele Di Fraia,Daniel A. Horke,Thomas Kierspel,Terence Mullins,Andreas Przystawik,Evgeny Savelyev,Joss Wiese,Tim Laarmann,Jochen Küpper,Daniel Rolles +25 more
TL;DR: In this paper, the authors present a high-harmonic source driven by a 100 kHz fiber laser system, which delivers 1011 photons/s in a single 1.3 eV bandwidth harmonic at 68.6 eV.

TL;DR: A novel high-harmonic source driven by a 100 kHz fiber laser system, which delivers 1011 photons/s in a single 1.3 eV bandwidth harmonic at 68.6 eV, paves the way for time-resolved studies of the dissociation dynamics of inner-shell ionized molecules in a coincidence detection scheme.

Acousto-optic pulse picking scheme with carrier-frequency-to-pulse-repetition-rate synchronization
Oliver de Vries,Tobias Saule,Marco Plötner,Fabian Lücking,Tino Eidam,Armin Hoffmann,Arno Klenke,Steffen Hädrich,Jens Limpert,Simon Holzberger,Thomas Schreiber,Ramona Eberhardt,Ioachim Pupeza,Andreas Tünnermann +13 more
TL;DR: A pulse picking technique based on a travelling-wave-type acousto-optic modulator having the AOM carrier frequency synchronized to the repetition rate of the original pulse train is introduced, rendering this technique suitable for applications requiring carrier-envelope phase stabilization.
22GW peak power femtosecond fiber CPA system
Arno Klenke,Arno Klenke,Steffen Hädrich,Steffen Hädrich,Tino Eidam,Tino Eidam,Jan Rothhardt,Jan Rothhardt,Marco Kienel,Marco Kienel,Armin Hoffmann,Stefan Demmler,Thomas Gottschall,Jens Limpert,Jens Limpert,Jens Limpert,Andreas Tünnermann,Andreas Tünnermann,Andreas Tünnermann +18 more
TL;DR: In this paper, a coherent combination of four parallel fiber amplifiers was used to record pulse energies and peak powers of 5.7 mJ and 22 GW with a chirped-pulse-amplification (CPA) laser system.
