Abstract
The effect of a nonuniform laser beam on the ablative acceleration of thin foils is investigated by using the fast2d laser-shell simulation code. The results show that laser nonuniformities with scale lengths 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.Keywords
