Figure 5. Photon yield and calculated pulse profiles.
(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.
