Femtosecond dynamics of optical properties of semiconductor

摘要

Dynamics of optical properties of semiconductor during action of femtosecond laser pulse is theoretically studied taking into account different types of electron emission. Calculated spatial distribution of dielectric permeability is modelled in multi-layered samples and experiment on surface plasmon resonance is performed. The experimental data is compared to surface periodic micro-structures experimentally observed in silicon under femtosecond laser action.
