Hyades modeling of ultrafast laser interactions with multilayer targets

Summary form only given. In experiments using femtosecond laser pulses, researchers with the Center for Ultrafast Optical Science (CUOS) have observed structure in multilayer target that reflects a combination of absorption dynamics and heat transport in the near-damage-threshold regime. We report attempts to model the laser interaction, heat transport, and ablation dynamics using a combination of 1D and 2D Hyades, a Lagrangian 3-temperature, 1-fluid hydrodynamic simulation code used within the high energy density physics community. The 2D simulations use a two dimensional mesh defined in R-Z coordinate space with a rotation axis of symmetry at R=0. The code will be compared to current experimental results from CUOS and will work with the experimental data to explore deeper dynamics of the system
