Laser-Plasma Simulation Environment

Calculations of laser–plasma instability important to laser-driven inertial confinement fusion (ICF) can only be made practical by using reduced physics models, i.e., by tailoring the model based on the problem (case by case). The essential physical processes must be retained in a way that is computationally efficient, so that the essential realism of multibeam interactions (most importantly, the correct dimensionality of space) can be simultaneously included. The LPSE (laser-plasma simulation environment) code system was constructed with this purpose in mind. The LPSE system provides a framework of physics packages that can be assembled for a particular problem.

Experimental Thomson-scattering spectra probing collective plasma-wave fluctuations driven by two-plasmon decay at two different wave numbers are shown here.
