We study transient charges formed in methane clusters following ionization by intense nearinfrared laser pulses. Cluster ionization by 400 fs (I = 1 × 10 W/cm) pulses is highly efficient, resulting in the observation of a dominant C ion contribution. The C ion yield is very small, but is strongly enhanced by applying a time-delayed weak near-infrared pulse. We conclude that most of the valence electrons are removed from their atoms during the laser-cluster interaction, and that electrons from…

The ionization of nanoscale clusters by intense laser pulses is fundamentally different from the ionization of atoms or small molecules. Laser energy is efficiently absorbed by clusters, transforming…

The results indicate that the LES emission occurs after significant nanoplasma expansion, and that it is a generic phenomenon in intense laser nanoparticle interactions, which is likely to influence the formation of highly charged ions.

A simple model is proposed to rationalize the data and identify two separate channels leading to the formation of excited hydrogen and three different phases of molecular fragmentation that are clearly distinguished by the effect of the probe laser on the ionic and electronic yield.
