摘要：

The Kramers-Kronig (KK) dispersion relation has been proved to hold between independently measured spectra of the phase shift phi(omega) and the modulus \chi(3)(omega)\ of third-order electric susceptibility chi(3) (=\chi(3)\e(iphi)) for the third-order harmonic generation in silicon-based polymer poly(dihexylsilane) (PDHS) films, providing a direct experimental substantiation of the reciprocal KK relations in the non-linear optical solids. The reciprocal dispersion relations have been also found to hold for the real and imaginary parts of chi(3) in PDHS films.
