Abstract

The time-resolved X-ray emission recorded from a plasma produced by a Nd laser at high intensity (>1014 W/cm2) shows successive bursts. They are correlated with the pulsation of the back-scattered second harmonic spectrum obtained during the same shot. Both results show that the plasmons resonantly excited at the critical surface by the laser waves can undergo quasiperiodically the collapse process.
