Journal ArticleDOI
Taking Two-Photon Excitation to Exceptional Path-Lengths in Photonic Crystal Fiber
TL;DR: In this article, the authors used two-photon-excited fluorescence to directly visualize the excitation path, and they showed that confinement of both laser beam and sample solution within the 20 μm hollow core of a photonic crystal fiber allowed TPE to be sustained over an extraordinary path-length of more than 10 cm.
Journal ArticleDOI
Resonant radiation and collapse of ultrashort pulses in planar waveguides
TL;DR: It is found that the process of pulse collapse enhances the emission of so-called resonant radiation, providing an efficient mechanism of energy transfer from solitonic to dispersive waves and leading to suppression of the collapse.
Journal ArticleDOI
Excitation of higher-order modes in optofluidic photonic crystal fiber.
Andrei Ruskuc,Philipp Koehler,Marius A. Weber,Ana Andres-Arroyo,Michael H. Frosz,Philip St. J. Russell,Tijmen G. Euser +6 more
TL;DR: Higher-order modes up to LP33 are controllably excited in water-filled kagomé- and bandgap-style hollow-core photonic crystal fibers and provide a framework for spatially-resolved sensing in HC-PCF microreactors and fiber-based optical manipulation.
Journal ArticleDOI
Sub-40 fs pulses at 1.8 µm and MHz repetition rates by chirp-assisted Raman scattering in hydrogen-filled hollow-core fiber
TL;DR: In this article, the authors reported the generation of sub-40 fs pulses at 1.8 µm, with quantum efficiencies of 50% and without the need for postcompression, in hydrogen-filled, hollow-core photonic crystal fiber pumped by a commercial high-repetition-rate 300 fs fiber laser at 1030 nm.
Journal ArticleDOI
Carrier-envelope-phase-stable soliton-based pulse compression to 4.4 fs and ultraviolet generation at the 800 kHz repetition rate.
Alexey Ermolov,Christian Heide,Philip Dienstbier,Felix Köttig,Francesco Tani,Peter Hommelhoff,Philip St. J. Russell +6 more
TL;DR: In this article, a femtosecond supercontinuum extending from the ultraviolet to the near-infrared spectrum and detection of its carrier-envelope phase (CEP) variation by f-to-2f interferometry was reported.
