摘要：

We report experimental evidence of ion-ion acoustic instability in laser-produced astrophysically relevant plasma. Irradiation of a copper foil with a short (2 ps) intense (10(17) W cm(-2)) laser pulse generates dense hot plasma, whose expansion into the rarefied preplasma generates the electrostatic collisionless shock. A shock-reflected ion beam penetrates through the shock upstream excites the ion-ion acoustic instability. The shock oscillation electric field and the instability filamentary modulation are monitored by proton radiography. Particle-in-cell and particle-tracing simulations reproduce the experimental observation.
