Microwave Modeling of Moderate Power Laser-Plasma Interactions

  • Chapter
Laser Interaction and Related Plasma Phenomena

Abstract

A critical issue in laser driven fusion pellets is the degradation in fusion yield due to plasma collective effects. We are using microwave driven low density plasmas to model1 some of the collective effects that degrade pellet performance. We have measured hot electron production due to resonance absorption,2 the ion acoustic decay (IAD) instability,3 and the two plasmon decay instability.4 Careful attention is given to scaling laws and the effect of boundary conditions so that our results apply to an important range of variables that occur in a laser driven pellet.
