Journal ArticleDOI
Superballistic growth of the variance of optical wave packets
Simon Stützer,Tsampikos Kottos,Andreas Tünnermann,Stefan Nolte,D. N. Christodoulides,Alexander Szameit +5 more
TL;DR: It is experimentally demonstrated that hybrid ordered-disordered photonic lattices can generate faster than the ballistic growth of the second moment of a spreading wave packet for parametrically large time intervals.
Journal ArticleDOI
Two-dimensional solitons at interfaces between binary superlattices and homogeneous lattices
Matthias Heinrich,Yaroslav V. Kartashov,L. P. R. Ramirez,Alexander Szameit,Felix Dreisow,Robert Keil,Stefan Nolte,Andreas Tünnermann,Victor A. Vysloukh,Lluis Torner +9 more
TL;DR: In this paper, the authors report on the experimental observation of two-dimensional surface solitons residing at the interface between a homogeneous square lattice and a superlattice that consists of alternating "deep" and "shallow" waveguides.
Proceedings ArticleDOI
150 W Nd/Yb codoped fiber laser at 1.1 /spl mu/m
Jens Limpert,Andreas Liem,S. Höfer,Holger Zellmer,Andreas Tünnermann,Sonja Unger,Sylvia Jetschke,H.-R. Muller +7 more
TL;DR: In this paper, a double-closeness double-clad fiber was demonstrated at two separated diode laser wavelengths (808 nm and 940 nm) with a combined output at 1.1 /spl mu/m.
Journal ArticleDOI
High-energy soliton pulse generation with a passively mode-locked Er/Yb-doped multifilament-core fiber laser
Bülend Ortaç,Jens Limpert,Sylvia Jetschke,Sonja Unger,Volker Reichel,Johannes Kirchhof,Andreas Tünnermann,Andreas Tünnermann +7 more
TL;DR: In this article, the authors reported the generation of high-energy short pulses from a mode-locked erbium/ytterbium-doped large-mode-area multifilament-core fiber laser operating in the purely anomalous dispersion regime.
Journal ArticleDOI
Phase stabilization of spatiotemporally multiplexed ultrafast amplifiers
TL;DR: A mitigation strategy based on a temporally gated error signal acquisition is derived and demonstrated, enabling to stabilize laser systems with arbitrary numbers of amplifier channels and optical delay lines.
