Plot of Ion energies from 14000 atom Xe clusters irradiated
by two pulses of different wavelengths as the delay between the two pulses is varied. The 780 nm (IR) pulse is 260 fs long and has a peak intensity of
6 ´ 1014 W cm-2,
while the 390 nm (blue) pulse is 185 fs long and has a peak intensity of
4 ´ 1015 W cm-2.
