Direct Laser Ion Acceleration and Above-Threshold Ionization at Intensities from $10^{21}$ W/cm${}^2$ to $3\times 10^{23}$ W/cm${}^2$

Andrew Yandow, Toma Toncian, Todd Ditmire

Calculations on the dynamics of ions and electrons in near-infrared laser fields at intensities up to $3\times 10^{23}$ W/cm${}^2$ are presented. We explore the acceleration of ions…
