Abstract
The linear stability analysis of unsteady ablation fronts is carried o ut for a semi-infinite uniform medium. For a laser accelerated target, it is shown that a properly selected modulation of the laser intensit y can lead to the dynamic stabilization or growth-rate reduction of a large portion of the unstable spectrum. The theory is in qualitative a greement with the numerical results obtained by using the two-dimensio nal hydrodynamic code ORCHID.
