TL;DR: In this paper, a three-cycle multi-millijoule pulse amplifier with 318 W power was reported. But this was achieved by compressing pulses of a Yb-fiber chirped pulse amplifier in a 6 m long stretched flexible hollow fiber.
Journal ArticleDOI
Carrier-envelope phase stable few-cycle laser system delivering more than 100 W, 1 mJ, sub-2-cycle pulses.
Steffen Hädrich,Evgeny Shestaev,Maxim Tschernajew,Fabian Stutzki,Nico Walther,Florian Just,Marco Kienel,Imre Seres,Péter Jójárt,Zsolt Bengery,Barnabás Gilicze,Zoltán Várallyay,Á. Börzsönyi,Michael Müller,Christian Grebing,Arno Klenke,Dominik Hoff,Gerhard G. Paulus,Tino Eidam,Jens Limpert +19 more
TL;DR: In this paper , a fiber-chirped-pulse amplifier system with a two-stage multipass-cell compression was presented to achieve sub-2-cycle (5.8) and sub-1.07"mJ pulses at 100 kHz centered at 1030"nm with excellent spatial beam quality.
Journal ArticleDOI
Tailoring soliton fission at telecom wavelengths using composite-liquid-core fibers
Mario Chemnitz,Saher Junaid,Nico Walther,Ramona Scheibinger,Kay Schaarschmidt,Jens Kobelke,Markus A. Schmidt +6 more
TL;DR: It is shown numerically that mixtures of organic and inorganic solvents in silica capillaries yield anomalous dispersion and reasonable nonlinearity at telecommunication wavelengths.
Journal ArticleDOI
Carrier-envelope offset stable, coherently combined ytterbium-doped fiber CPA delivering 1 kW of average power
Evgeny Shestaev,Steffen Hädrich,Nico Walther,Tino Eidam,Arno Klenke,Imre Seres,Z. Bengery,Péter Jójárt,Zoltán Várallyay,Adam Borzsonyi,Jens Limpert +10 more
TL;DR: To the best of the knowledge, this is the first demonstration of a coherently combined laser system delivering an outstanding average power and high CEO stability at the same time.
Proceedings ArticleDOI
3.2-mJ sub-10-fs pulses at 100 kHz
Steffen Hädrich,Peter Šimon,Tamas Nagy,Andreas Blumenstein,Nico Walther,Marco Kienel,Evgeny Shestaev,Fabian Stutzki,Christian Gaida,Sven Breitkopf,Péter Jójárt,Zoltán Várallyay,Karoly Osvay,Tino Eidam,Jens Limpert +14 more
TL;DR: In this article, the authors presented sub-10fs, 3.2mJ pulses at 100kHz repetition-rate using a 6-m-long stretched flexible capillary.
