Journal ArticleDOI
On the study of pulse evolution in ultra-short pulse mode-locked fiber lasers by numerical simulations.
TL;DR: Different regimes of mode-locking obtained by varying the intra-cavity dispersion and saturation energy of the gain fiber are revised and it is shown that a regime producing linearly chirped parabolic pulses known from self-similar evolution is embedded in the wave-breaking free mode- locking regime.
Journal ArticleDOI
Thermo-optical properties of air-clad photonic crystal fiber lasers in high power operation.

TL;DR: In this paper, the authors investigated the thermo-optical behavior of air-clad ytterbium-doped large-mode-area photonic crystal fiber lasers.
Journal ArticleDOI
Hybrid soliton dynamics in liquid-core fibres.

TL;DR: Experimental evidence for hybrid solitons – a type of solitary wave, which emerges as a result of a strong non-instantaneous nonlinear response in CS2-filled liquid-core optical fibres is reported, demonstrating efficient soliton-driven supercontinuum generation.
Journal ArticleDOI

TL;DR: A table-top, broadband, coherent mid-infrared light source that offers a compact and bright alternative to a synchrotron in the 4−18 µm spectral range has been developed by a German-US research team.
