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-…
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…
Attosecond pulse shaping using partial phase matching
Dane R. Austin, Jens Biegert
We propose a method for programmable shaping of the amplitude and phase of the XUV and x-ray attosecond pulses produced by high-order harmonic generation. It overcomes the bandwidt…
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…
Multi-octave supercontinuum from mid-IR filamentation in bulk
F. Silva, D. Austin, A. Thai +4
In supercontinuum generation, various propa- gation effects combine to produce a dramatic spec- tral broadening of intense ultrashort optical pulses with far reaching possibilities…
Vectorial Phase Retrieval for Linear Characterization of Attosecond Pulses
Oren Raz, Osip Schwartz, Dane Austin +7
The waveforms of attosecond pulses produced by high-harmonic generation carry information on the electronic structure and dynamics in atomic and molecular systems. Current methods…
Shaping speckles: spatio-temporal focussing of an ultrafast pulse through a multiply scattering medium
David J. McCabe, Ayhan Tajalli, Dane R. Austin +4
The multiple scattering of coherent light is a problem of both fundamental and applied importance. In optics, phase conjugation allows spatial focussing and imaging through a multi…
Space-time coupling of shaped ultrafast ultraviolet pulses from an acousto-optic programmable dispersive filter
David J. McCabe, Dane R. Austin, Ayhan Tajalli +3
A comprehensive experimental analysis of spatio-temporal coupling effects inherent to the acousto-optic programmable dispersive filter (AOPDF) is presented. Phase and amplitude mea…
Measuring sub-Planck structural analogues in chronocyclic phase space
Dane R. Austin, Tobias Witting, Ian A. Walmsley
The phase space structure of certain quantum states reveals structure on a scale that is small compared to the Planck area. Using an analog between the wavefunction of a single pho…
Ultrashort pulse characterization by spectral shearing interferometry with spatially chirped ancillae
Tobias Witting, Dane R. Austin, Ian A. Walmsley
We report a new version of spectral phase interferometry for direct electric field reconstruction (SPIDER), which enables consistency checking through the simultaneous acquisition…
