We demonstrate experimentally that the device accurately retrieves the pulse-front tilt caused by angular dispersion of two-cycle pulses. We then use the technique to characterize 500\&\#x02013;650 \&\#x003BC;J pulses from a hollow fiber pulse compressor, with durations as short as 7.1 fs (1.3 optical cycles).},

We find that the chemical substitutions have a strong influence on the amplitude and phase of the emission from the highest occupied molecular orbital{,} despite having a small influence on the orbital itself. We show that this influence is due to the tunnel ionization step{,} which depends critically on the sign and amplitude of the asymptotic part of the wave function. We discuss how these effects would manifest in phase-sensitive high-harmonic generation spectroscopy experiments.},

It overcomes the bandwidth limitations of existing spectral filters and enables removal of the intrinsic attosecond chirp as well as the synthesis of pulse sequences. It is based on partial phase matching using a longitudinally addressable modulation. Although the method is in principle applicable to any form of partial phase matching, we focus on quasi-phase matching using a counterpropagating pulse train. We present simulations of the production of isolated attosecond pulses at 250 eV, including a 31 as transform-limited pulse, tunably chirped pulses and double pulses.},

    abstract = { We investigate quantum trajectory control in high-order harmonic generation using an additional orthogonally polarised second harmonic field. By controlling the relative phase between this field and the fundamental, we are able to suppress and enhance particular electron trajectories which results in a modulation of the harmonic emission. We observe a phase shift of the modulation between the short and long trajectories that is different for adjacent odd and even harmonics. These results show qualitative agreement with a full propagation calculation where the single atom response was obtained from the strong field approximation and the main results are explained by consideration of a single atom quantum orbit picture. },

    abstract = {Propagation of an ultrashort laser pulse through a scattering medium forms a speckle pattern in the spatio-spectral domain. This pattern arises from the contribution of the randomly phased electric fields associated with the different optical paths in the medium. Studying the speckle field provides information both about the diffusion properties of the medium and spatio-temporal control of the transmitted or scattered light. In this paper a spatio-temporal characterization of the near-IR 120?fs pulse transmitted through a thick strongly scattering medium is undertaken using spatially and spectrally resolved Fourier-transform interferometry (SSI). The advantages of SSI over conventional pulse measurement techniques are discussed. The diffusion properties of the scattering samples are measured. We find a good agreement between our measured diffusion properties and those obtained using another method. The implications of this measurement technique are discussed.},

    abstract = {An acousto-optic pulse shaper has been used to characterize few-cycle pulses generated in a hollow-core fiber. A grism pair precompensates for the dispersion of the acousto-optic crystal, allowing the full pulse-shaping window to be used for replica generation rather than self-compensation. A 9.4?fs pulse was measured, the shortest ever measured with an acousto-optic pulse shaper, to our knowledge.},

Tilted replicas of the driving laser pulse are produced by a Mach--Zehnder interferometer, producing separate focii in the target.

A comprehensive set of spatial profiles, resolved by harmonic order, validate the technique and reveal the interplay of single-atom and macroscopic effects.},

Phase and amplitude measurements of the AOPDF transfer function are performed using spatially and spectrally resolved interferometry. Spatiotemporal and spatio-spectral coupling effects are presented for a range of shaped pulses that are commonly used in quantum control experiments. These effects are shown to be attributable to a single mechanism: a group-delay-dependent displacement of the shaped pulse. The physical mechanism is explained, and excellent quantitative agreement between the measured and calculated coupling speed is obtained. The implications for quantum control experiments are discussed.},

Starting with the principle of divergent illumination of the grating, which removes astigmatism at one chosen wavelength, we obtain design equations for the distance from the grating to the focusing mirror and the detector angle that remove the astigmatism to first order in wavelength. Experimentally, we demonstrate near diffraction-limited performance from 740 to 860 nm and over a 5 mm transverse spatial extent, while ray-tracing calcula- tions show that barring finite-aperture and detector size limitations, this range extends from 640 to 900 nm and over 10 mm transversely. Our technique requires no additional optics and uses standard off-the- shelf components.},

We show that dispersive waves are primarily generated over a short region of high temporal compression. Despite the apparent complexity of the pump pulse in this region, we show that the dynamics of dispersive wave generation are dominated by a single fundamental soliton. However, any straightforward application of the theory that is thought to describe the blue emission, considerably underestimates the frequency shift. We show that in fact the red-shift of the soliton, caused by spectral recoil from the growing dispersive wave, causes an additional blue-shift of the resonant frequency which is in good agreement with full simulations.},
