First-Principles Calculations of the Electron Dynamics During Femtosecond Laser Pulse Train Material Interactions
This Letter presents first-principles calculations of nonlinear electron-photon interactions in crystalline SiO₂ ablated by a femtosecond pulse train that consists of one or multiple pulses. A real-time and real-space time-dependent density functional method (TDDFT) is applied for the descriptions of electrons dynamics and energy absorption. The effects of power intensity, laser wavelength (frequency) and number of pulses per train on the excited energy and excited electrons are investigated. © 2011 Elsevier B.V. All rights reserved.
