Contemporary ultrafast science requires reliable sources of high-energy few-cycle light
pulses. Currently two methods are capable of generating such pulses: post compression of …

Intense ultrashort light pulses comprising merely a few wave cycles became routinely
available by the turn of the millennium. The technologies underlying their production and …

The motion of electrons on the atomic scale has been hidden from direct experimental
access until recently. We review the revolution in technology that opened the door to real …

Attosecond pulses are generated by a macroscopic number of ionizing atoms interacting
with a focused laser pulse, via the process of high harmonic generation. The physics of their …

Filamentation of ultrashort laser pulses in the atmosphere offers unique opportunities for
long-range transmission of high-power laser radiation and standoff detection. With the …

The state of the art of investigations on filamentation of a high-power femtosecond laser
radiation in transparent media is reviewed. The physical picture of this phenomenon is …

The physics of strong-field applications requires driver laser pulses that are both energetic
and extremely short. Whereas optical amplifiers, laser and parametric, boost the energy …

Dispersion of femtosecond laser pulses propagating in Ar, He, Kr, N_2, Ne, Xe, and their
mixtures is measured by spectrally and spatially resolved interferometry. By varying the gas …

High-order harmonic generation from atoms ionized by femtosecond laser pulses has been
a promising approach for the development of coherent short-wavelength sources. However …

Femtosecond laser pulses filamenting in various gases are shown to generate long-lived
quasi-stationary cylindrical depressions or 'holes' in the gas density. For our experimental …
