The advent of ultraintense laser pulses generated by the technique of chirped pulse
amplification (CPA) along with the development of high-fluence laser materials has opened …

Laser excitation of nanometer-sized atomic and molecular clusters offers various
opportunities to explore and control ultrafast many-particle dynamics. Whereas weak laser …

Ultracold neutral plasmas formed by photoionizing laser-cooled atoms near the ionization
threshold have electron temperatures in the 1–1000K range and ion temperatures from tens …

The evolution of large atomic clusters exposed to a super-intense ultrashort laser pulse is
considered. Cluster excitation results from the interaction of its electron subsystem with the …

An approach for accelerating ions, with the use of a cluster-gas target and an ultrashort
pulse laser of 150-mJ energy and 40-fs duration, is presented. Ions with energy 10–20 MeV …

We report optical absorption imaging of ultracold neutral strontium plasmas. The ion
absorption spectrum determined from the images is Doppler broadened and thus provides a …

We report the observation and characterization of a new nonresonant strong field ionization
mechanism in polyatomic molecules: Nonadiabatic multi-electron (NME) dynamics. The …

We study experimentally the line of a single quantized vortex in a rotating prolate Bose-
Einstein condensate confined by a harmonic potential. In agreement with predictions, we …

Abstract Clusters of 2× 10 3 to 4× 10 4 Ar atoms are Coulomb exploded in intense (up to 8×
10 15 W cm− 2) laser fields. The dependence of multiply charged argon ion energies on the …

The effect of spatial and other external confinements on the ground and excited state energy
levels of many electron atoms, ions and exotic systems is discussed. Special emphasis is …
