Interplay Between Mixed and Pure Exciton States Controls Singlet Fission in Rubrene Single Crystals
Dmitry R. Maslennikov, Marios Maimaris, Haoqing Ning +9
Singlet fission (SF) is a multielectron process in which one singlet exciton S converts into a pair of triplet excitons T+T. SF is widely studied as it may help overcome the Shockl…
Temporal characterization of long quantum-path high harmonics
A. Carpeggiani, B. Bodi, E. S. Skantzakis +5
We measure for the first time the duration of long-quantum path EUV high harmonics produced in xenon gas. The long-quantum path contribution to the high-harmonic signal was careful…
Correlation Driven Transient Hole Dynamics Resolved in Space and Time in the Isopropanol Molecule
T. Barillot, O. Alexander, B. Cooper +46
The possibility of suddenly ionized molecules undergoing extremely fast electron hole dynamics prior to significant structural change was first recognized more than 20 years ago an…
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…
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-…
Attosecond physics at the nanoscale
M. F. Ciappina, J. A. Pérez-Hernández, A. S. Landsman +22
Recently two emerging areas of research, attosecond and nanoscale physics, have started to come together. Attosecond physics deals with phenomena occurring when ultrashort laser pu…
Strong-field ionization of clusters using two-cycle pulses at 1.8~m
Bernd Schütte, Peng Ye, Serguei Patchkovskii +7
The interaction of intense laser pulses with nano-scale particles leads to the production of high-energy electrons, ions, neutral atoms, neutrons and photons. Up to now, investigat…
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…
Single-shot implementation of dispersion-scan for the characterization of ultrashort laser pulses
Davide Fabris, Warein Holgado, Francisco Silva +3
We demonstrate a novel, single-shot ultrafast diagnostic, based on the dispersion-scan (d-scan) technique. In this implementation, rather than scanning wedges to vary the dispersio…
Simultaneous VUV and XUV pulse generation and characterization for attosecond pump probe experiments
D. Fabris, W. A. Okell, D. Walke +3
We report the generation and characterization of isolated attosecond XUV and VUV pulses generated simultaneously via HHG driven by few-cycle pulses using an in-line dual gas target…
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…
Optimisation of Quantum Trajectories Driven by Strong-field Waveforms
S. Haessler, T. Balčiūnas, G. Fan +9
Quasi-free field-driven electron trajectories are a key element of strong-field dynamics. Upon recollision with the parent ion, the energy transferred from the field to the electro…
Spatio-temporal characterization of mid-infrared laser pulses with spatially encoded spectral shearing interferometry
Tobias Witting, Sebastien J. Weber, John W. G. Tisch +1
We report on the spatially resolved full amplitude and phase characterization of mid-infrared high intensity laser pulses generated in a three stage OPA. We use a spatially-encoded…
Molecular internal dynamics studied by quantum path interferences in high order harmonic generation
Amelle Zair, Thomas Siegel, Suren Sukiasyan +9
We investigate how short and long electron trajectory contributions to high harmonic emission and their interferences give access to intra-molecular dynamics. In the case of unalig…
