TL;DR: The results show that the temporal coherence of light pulses is transferred to free electron wave packets, thus opening the door to a whole variety of exciting experiments.
Journal ArticleDOI
High-harmonic generation and plasma radiation from water microdroplets
TL;DR: In this paper, the authors studied the emission of XUV radiation from water microdroplets under excitation with either a single or a pair of intense femtosecond laser pulses (Ti:Sa, 80fs, ∼1014 W/cm2, 800nm, 1.kHz).
Journal ArticleDOI
Ellipticity dependence of atomic and molecular high harmonic generation
TL;DR: The dependence on the ellipticity of the fundamental laser radiation for an atomic and a molecular system was investigated in this paper, and it was shown that the harmonic yield decreases slower for the molecule than for the atom.
Journal ArticleDOI
High harmonic generation at 1 kHz repetition rate with a pulsed valve
TL;DR: In this paper, a piezoelectric pulsed valve together with a femtosecond Ti:Sapphire laser both operating at 1 kHz were employed to generate high harmonic radiation in xenon and argon.
Journal ArticleDOI
Atomic and molecular high-harmonic generation: a comparison of ellipticity dependence based on the three-step model
TL;DR: In this article, the authors compare high-harmonic generation for an atomic and a diatomic molecular system, by studying the cllipticity dependence for the generation process in the two representative gases Ar and N2 as they have almost identical ionization potential and average static polarizabilities.
