Column 1, results for β2 = −1.0 ps2 m−1, β3 = 4.5 ps3 m−1. a Applied linear (orange) dispersion relation with measured output spectrum (blue). b Measured spectrogram. c Retrieved real electric field (teal) and temporal phase (yellow). Columns 2 (d–f) and 3 (g–i) are similar, but for the opposite-signed odd-order β3 = −4.5 ps3 m−1, and an even-order β4 = 22.8 ps4 m−1 perturbation respectively.
