Attosecond pulse walk-off in high-order harmonic generation.
We study the influence of the generation conditions on the group delay of attosecond pulses in high-order harmonic generation in gases. The group delay relative to the fundamental field is found to decrease with increasing gas pressure in the generation cell, reflecting a temporal walk-off due to the dispersive properties of the nonlinear medium. This effect is well reproduced using an on-axis ...
متن کاملChiral dichroism in bi-elliptical high-order harmonic generation
The application of strong bi-elliptically polarized laser fields to the generation of high-order harmonics in organic molecules offers exceptional opportunities for chiral recognition and chiral discrimination. These fields are made by combining an elliptically polarized fundamental, typically in the infrared range, with its counter-rotating second harmonic. Here we present a theoretical study ...
متن کاملAttosecond Pulses through High Harmonic Generation
“To fill a vacancy in a lower-lying atomic shell, an orbiting electron has to shed energy. If it follows the Auger process, the shell-hopping electron transfers its excess energy to a neighboring electron in the same shell. Left behind with too much energy, the neighbor quits the atom. The eviction takes a few tens to a few thousands of attoseconds (10^-18s)—at least that’s what the energy spec...
متن کاملSpectral signature of short attosecond pulse trains.
We report experimental measurements of high-order harmonic spectra generated in Ar using a carrier-envelope-offset (CEO) stabilized 12 fs, 800 nm laser field and a fraction (less than 10%) of its second harmonic. Additional spectral peaks are observed between the harmonic peaks, which are due to interferences between multiple pulses in the train. The position of these peaks varies with the CEO ...
متن کاملPhotonic streaking of attosecond pulse trains
High harmonic radiation, produced when intense laser pulses interact with matter, is composed of a train of attosecond pulses. Individual pulses in this train carry information on ultrafast dynamics that vary from one half-optical-cycle to the next. Here, we demonstrate an all-optical photonic streaking measurement that provides direct experimental access to each attosecond pulse by mapping emi...
