Abstract
In this paper, we are focused on the understanding the underlying physical mechanisms of femtosecond laser interactions with metallic and multi-layer optical materials. The results of the numerical modeling provide an estimation of damage and/or ablation threshold for different laser parameters (pulse duration, fluence, angle of incidence, polarization) and target material properties (metal, dielectric, or multilayer with variable metal layer thickness). These results are compared with the experimental measurements of the thresholds obtained by using different techniques. In particular, dielectric ionization and ablation mechanisms are analyzed based on the experimental findings.
