Two-fluid plasma model for ultrashort laser-induced electron-hole nanoplasmas
Résumé
We present a two-fluid plasma model to describe localized
interaction, at submicrometer scale, of highly focused ultrashort
laser pulses within dielectrics and semiconductors. This model
includes transport of the electron-hole plasma, electron-hole
scattering, photoionization, impact ionization, and interactions
between charge carriers and phonons. We start with a plasma kinetic
description, and we consistently derive the two-fluid plasma model
equations. Our numerical results highlight that transport of the
electron-hole plasma can strongly affect the plasma density profile
in the case of extremely localized interaction.
