    Abstract

    Strong four-photon absorption corresponding to Im[chi((tau))((-)omega; w, (-)omega, omega, (-)omega, omega, (-)omega, omega)] has been measured for the first time to the authors' knowledge with 100-fs pulses at 1600 nm in the single-crystal polymer poly[bis(p-toluene sulfonate)] of 2,4-hexadiyne-1,6-diol. The transition involved is from the even-symmetry ground state into the vibronic subband of the dominant, even-symmetry, excited two-photon state at an energy of 2.7 eV.
