The mechanism of high harmonic generation in liquid alcohol
Oliver Alexander, Jonathan C. T. Barnard, Esben W. Larsen +10
The observation of non-perturbative harmonic emission in solids from ultrashort laser pulses [1] sparked a wave of studies [2,3] as a probe of charge carrier dynamics in solids und…
Optical Parametric Amplification of Mid-Infrared Few-Cycle Pulses
Adam S Wyatt, Paloma Matía-Hernando, Allan S Johnson +8
We describe Ti:Sapphire pumped optical parametric amplification of carrier-envelope phase stabilized few-cycle (fs) mid-infrared pulses in type I -barium borate. Experiment…
Tunable Isolated Attosecond X-ray Pulses with Gigawatt Peak Power from a Free-Electron Laser
Joseph Duris, Siqi Li, Taran Driver +31
The quantum mechanical motion of electrons in molecules and solids occurs on the sub-femtosecond timescale. Consequently, the study of ultrafast electronic phenomena requires the g…
Direct characterisation of tuneable few-femtosecond dispersive-wave pulses in the deep UV
Christian Brahms, Dane R. Austin, Francesco Tani +6
Dispersive wave emission (DWE) in gas-filled hollow-core dielectric waveguides is a promising source of tuneable coherent and broadband radiation, but so far the generation of few-…
Self-referenced characterization of space-time couplings in near single-cycle laser pulses
T. Witting, D. R. Austin, T. Barilot +5
We report on the characterization of space-time couplings in high energy sub-2-cycle 770nm laser pulses using a self-referencing single-shot method. Using spatially-encoded arrange…
Carrier-envelope phase stability of hollow-fibers used for high-energy, few-cycle pulse generation
William A. Okell, Tobias Witting, Davide Fabris +9
We investigated the carrier-envelope phase (CEP) stability of a hollow-fiber setup used for high-energy, few-cycle pulse generation. Saturation of the output pulse energy is observ…
