Figure 5. Photon yield and calculated pulse profiles.

Figure 5

(a) Comparison of photon yields on target. Chirped mirror reflection profile from24 (b). Simulated pulse profile in the case without wavefront rotation, after transmission through a 400-nm Al filter, leading to a pre/post-pulse contrast of 1:5. (c) Simulated pulse profile in the case of wavefront rotation, leading to an increased pre/post-pulse contrast of 1:20.
