Steffen Hädrich,Steffen Hädrich,Arno Klenke,Arno Klenke,Jan Rothhardt,Jan Rothhardt,Manuel Krebs,Armin Hoffmann,Oleg Pronin,Vladimir Pervak,Jens Limpert,Jens Limpert,Jens Limpert,Andreas Tünnermann,Andreas Tünnermann,Andreas Tünnermann +15 more
TL;DR: In this paper, a new table-top coherent extreme ultraviolet (EUV) source based on phase-matched high-harmonic generation using a fiber laser is presented. But the authors did not specify the number of photons in the 25 −40 eV range.
Journal ArticleDOI
530 W, 1.3 mJ, four-channel coherently combined femtosecond fiber chirped-pulse amplification system
Arno Klenke,Sven Breitkopf,Marco Kienel,Thomas Gottschall,Tino Eidam,Steffen Hädrich,Jan Rothhardt,Jens Limpert,Andreas Tünnermann +8 more
TL;DR: A femtosecond fiber laser system comprising four coherently combined large-pitch fibers as the main amplifier and an excellent beam quality and efficiency have been obtained.
Journal ArticleDOI

TL;DR: An ultrafast fiber chirped-pulse amplifier comprising eight coherently combined amplifier channels is presented and has proven suitable for demanding scientific applications.
Journal ArticleDOI
Energetic sub-2-cycle laser with 216 W average power
Steffen Hädrich,Marco Kienel,Michael Müller,Arno Klenke,Jan Rothhardt,Robert Klas,Thomas Gottschall,Tino Eidam,András Drozdy,Péter Jójárt,Zoltán Várallyay,Eric Cormier,Karoly Osvay,Andreas Tünnermann,Jens Limpert +14 more
TL;DR: Two-stage nonlinear compression of a 660 W femtosecond fiber laser system is utilized to achieve unprecedented average power levels of energetic ultrashort or even few-cycle laser pulses, expected to significantly advance the fields of high harmonic generation and attosecond science.
Journal ArticleDOI
