Abstract

We present detailed studies of femtosecond transient holography in conjugated polymer blends and superlattices, using tunable non-degenerate four-wave mixing. Combined with spectral transient absorption studies, these experiments allow determination of the complex nonlinear index of refraction over the photon energy range from 1-3 eV
