Abstract
Ionization of matter with gold nanodopes by intense (∼1017−1018 W/cm2) short (0.1 ps) laser pulses is studied numerically with particle-in-cell (PIC) method; resonant crossed nanoantennas are embedded in the hydrogen-rich dense media. We model and explore the dynamics of ionization and ion energy acquisition during the radiation pulse passage in matter with nanoantenna. Influence of the field intensity on the resonance characteristics is studied to identify the optimal conditions for maximizing proton energy. The results are intended to optimize laser-driven ionization, initiate and control Laser-Induced Nanofusion (LIN) at nanoscale.
