Numerical modeling of quantum beam generation from ultra-intense laser-matter interactions

摘要

When intense laser beams interact with solid targets, high-energy photons are effectively generated via radiation reaction effect. These photons receive a large portion of the incident laser energy, and the energy transport by photons through the target is crucial for the understanding of the laser-matter interactions. In order to understand the energy transport, we newly developed a Particle-in-Cell code which includes the photon-matter interactions by introducing photon macro-particles. Test simulations are performed and compared with simulations using a particle transport code, which shows a good agreement.
