(color online) Calculated output spectrum for different initial spectral noise. Panels (a), (b), and (c) are calculated for . Panels (d), (e), and (f) are calculated for . For panels (a) and (d), ; panels (b) and (e), ; and panels (c) and (f), . The FTL pulse duration of the input pulse is 8 fs. The initial chirp is 300 fs².
