Plasma perspective on strong field multiphoton ionization.
TL;DR: During strong-field multiphoton ionization, a wave packet is formed each time the laser field passes its maximum value, and one important parameter which determines the strength of these effects is the rate at which the wave packet spreads in the direction perpendicular to the laser electric field.

Observation of a Train of Attosecond Pulses from High Harmonic Generation
TL;DR: It is found that the harmonics are locked in phase and form a train of 250-attosecond pulses in the time domain, suggesting that Harmonic generation may be a promising source for attosecond time-resolved measurements.
Tunnel ionization of complex atoms and of atomic ions in an altemating electromagnetic field
TL;DR: In this article, an expression for the probability of tunnel ionization in an alternating field, of a complex atom and of an atomic ion that are in an arbitrary state, was derived in the quasiclassical approximation n* $1.

TL;DR: Ultrafast metrology reveals a 20-attosecond delay between photoemission from different electronic orbitals in neon atoms and theoretical models refined with the help of attosecond timing metrology may provide insight into electron correlations and allow the setting of the zero of time in atomic-scale chronoscopy with a precision of a few attose Cond.
