Abstract
By using an effective dielectric constant to modify the nanoplasma
model, the interactions of large Ar clusters with high-intensity
femtosecond laser pulses have been studied. It is shown that the
resonance absorption mechanism plays a predominant role in the
production of highly energetic argon ions, and the calculated mean
kinetic energy of Ar ions is in good agreement with our previous
experimental results. The scaling of mean kinetic energy and charge
states of Ar ions against cluster size and laser intensity has also
been analyzed. The results indicate the existence of optimum cluster
sizes and optimum laser intensities where the best coupling efficiency
of the laser energy can be obtained.
