Laser modeling is a computational and theoretical research field dedicated to simulating and analyzing the complex interactions between intense laser radiation and various forms of matter. This methodology investigates phenomena including laser energy absorption, transport, plasma dynamics, and induced material or nuclear responses, utilizing numerical algorithms and physical models. Its significance lies in enabling the prediction of experimental results, optimization of laser parameters and target configurations, and deepening the understanding of fundamental physical processes in high-energy density regimes and related applications like inertial confinement fusion.
