Two-photon saturation in the band gap of a molecular quantum wire.
The saturation of the strongest two-photon band accessible with photon energies in the band gap of a onedimensional pi-electron conjugated molecular single crystal is observed with 200-fs pulses for optical intensities of the order of 2 GW/cm(2).
