Effect of anti-crossings with cladding resonances on ultrafast nonlinear dynamics in gas-filled PCFs
Francesco Tani, Felix Köttig, David Novoa +2
Spectral anti-crossings between the fundamental guided mode and core wall resonances alter the dispersion in hollow-core anti-resonant-reflection photonic crystal fibers. Here we s…
Soliton-effect self-compressed single-cycle 9.6-W mid-IR pulses from a 21-W OPCPA at 3.25 μm and 160 kHz
Ugaitz Elu, Matthias Baudisch, Hugo Pires +6
We report a 21-W mid-IR OPCPA that generates 131-μJ and 97 fs (sub-9-cycle) pulses at 160 kHz repetition rate and at a centre wavelength of 3.25 μm. Pulse-to-pulse stability of the…
Continuously wavelength-tunable high harmonic generation via soliton dynamics
Francesco Tani, Michael H. Frosz, John C. Travers +1
We report generation of high harmonics in a gas-jet pumped by pulses self-compressed in a He-filled hollow-core photonic crystal fiber through the soliton effect. The gas-jet is pl…
PHz-wide spectral interference through coherent plasma-induced fission of higher-order solitons
F. Köttig, F. Tani, J. C. Travers +1
We identify a novel regime of soliton-plasma interactions in which high-intensity ultrashort pulses of intermediate soliton order undergo coherent plasma-induced fission. Experimen…
