Strongly Inhibited Rayleigh-Taylor Growth with 0.25-μm Lasers

It is shown through numerical simulation that the Rayleigh-Taylor growth rate for targets accelerated by laser ablation, is reduced below the classical value, ${\mathrm{}\left(\mathrm{kg}\right)\mathrm{}}^{\frac{1}{2}}$, by factors of 3-4 with 0.25-μm laser light. The simulation results are supported by an analytical expression for the growth rates. These results provide further evidence for the viability of high-aspect-ratio shells in direct-drive laser fusion.
