Modeling of Thermodiffusion Inertia in Metal Films Heated with Ultrashort Laser Pulses
Previously, we considered the analytical solution of nonlinear diffusion equation in two-dimensional surface. This allows us to consider the same nonlinear heat conduction equation for metals heated by a picosecond laser. After fast thermalization (within a few femtoseconds) of the laser energy and electron excitation in the conductivity band, electrons ballistically diffuse and transfer their ...
متن کاملNonlinear absorption of ultrashort laser pulses in thin metal films.
Self-consistent simulations of the ultrafast electron dynamics in thin metal films were performed. A regime of nonlinear oscillations was observed that corresponds to ballistic electrons bouncing back and forth against the films' surfaces. When an oscillatory laser field is applied to the film, the field energy is partially absorbed by the electron gas. Maximum absorption occurs when the period...
متن کاملModeling the Early Ionization of Dielectrics by Ultrashort Laser Pulses
In this paper, we present a model for propagation of intense and ultrashort laser pulses ionizing dielectrics. We consider early ionization so that this process is sufficiently weak to avoid requiring a complete description of the ionization process (e.g. the use of kinetic equations which are very expensive from a computational point of view). As the intensity of the field is small, one photon...
متن کاملOptimal control with ultrashort laser pulses
Coherent control is a new fascinating field subsuming theoretical and experimental efforts aiming at controlling quantum phenomena using the interaction with tailored laser fields. Building on the coherence property a quantum mechanical system is laser-driven into a specific quantum mechanical state or along a reaction pathway to a desired product. The needed pulse shape for a specific aim can ...
متن کاملTailored-Beam Ultrashort Laser Pulses
Laser pulses with picosecond and femtosecond durations are now indispensable tools in many scientific disciplines. These ultrashort pulses provide unique temporal resolutions for investigations of phenomena taking place in comparable time ranges. In addition, optical energies squeezed into such short time windows yield extremely high peak powers and intensities, paving the way to generate unpre...
