Figure 3

Comparison of fluence distributions (cross-sections across optical axis) achieved near focus. Fluence distributions for (a) single-pulse and (b) double-pulse irradiations at different incoming energy. (c) Fluence contributions of the second pulse in the double-pulse irradiation. (d) Fluence distributions for trains with different number of pulses at constant total energy of 26 nJ.
