Fast laser heating of electrons as a source of ion-acoustic oscillations

  • Published:
Journal of Russian Laser Research Aims and scope

Abstract

It is shown that heating of electrons due to the inverse bremsstrahlung absorption of high-power short-pulse laser radiation results in parametric generation of ion-acoustic waves. Dependences of the generation efficiency on the laser pulse duration and intensity are derived. The range of wave numbers where the amplitude of the ion-acoustic oscillations increases by more than an order of magnitude is determined.
