Particle-in-cell modeling of non-radiating states of laser-plasma

Abstract

In this work we study numerically, by means of Particle-in-Cell simulations, the formation of non-radiating configurations in a plasma, arising from the ionization of atomic gases by intense laser pulse Our simulation show that, after the release of a short terahertz pulse, a nearly non-radiating field and current configuration is formed, even though the charge and current distributions of plasma remain essentially time-dependent. In a plasma target emitting terahertz waves, such a non-radiating state is formed under the action of radiation. Our calculations suggest that formation of a non-radiating configuration occurs in a self-consistent way and can therefore affect the duration of the emitted terahertz pulse.
