Nonlocal Electron Transport in Laser Ablation

Electron transport plays an important role in laser-produced plasmas, especially in laser fusion plasmas, there are some issues to be solved related to the electron transport. The flux-inhibition is an important process in the 1-D problem. Also, in the 2-D problem, the spatial relaxation of the perturbation of the electron flux should be considered. These processes are closely related to the nonlocal electron transport where electron velocity distribution function is not Maxwellian. In order to simulate the nonlocal electron transport in the laser ablation process, we have developed the 1D and 2D nonlocal electron transport simulation codes based on the Fokker-Planck equations. We will compare results of the electron energy conduction calculated by the flux-limited Spitzer-Harm model and those based on the Fokker-Planck simulation in the 1D and 2D condition for the typical laser ablation condition.
