Simulation of laser beam nonuniformity effects

Creators

Description

We investigate the effect of a nonuniform beam on the ablative acceleration of thin foils using the FAST2D laser-shell simulation code. The results show that laser nonuniformities with scalelengths greater than the distance from the ablation surface to the critical surface would have a severe impact on drive pressure symmetry and hence on pellet gain
