Laser-plasma interactions in ultra-intense fields of colliding laser pulses — •Christoph Baumann and Alexander Pukhov — Institut für Theoretische Physik I, Heinrich-Heine-Universität, 40225 Düsseldorf, Deutschland
The continuous development of laser technology will open the door of studying laser-plasma interactions in fields with intensities above 1023 Wcm−2. In the so-called quantum-dominated regime, the plasma dynamics can change significantly due to the increasing influence of nonlinear Compton scattering and Breit-Wheeler pair production on the interaction process.
In the present work, we use PIC simulations to report about the interaction of a one micron thick plasma foil with two counter-propagating circularly-polarized laser pulses that have intensities up to the order of 1024 Wcm−2. We analyze the influence of pair production on the interaction process. In a second simulation setup, we report about the generation of a train of attosecond electron bunches within the interaction of the plasma target with two Laguerre-Gaussian laser pulses of ultra-high intensity.
