Investigating amplitude and phase coupling as a function of chirp. The amplitude of the fundamental was shaped according to the filled orange curve in (a), which shows the square of the input intensity. TSH (c) exhibits a strong dependence of the spectral amplitude as a function of input chirp. Because this amplitude-phase coupling is absent in FSH (c), all SH spectra remain constant, like the black line in (a). All spectral features transfer directly to the SH.
