Paper Abstract

We have used the z-scan technique to determine the sign and magnitude of the off-resonant n2 and two photon absorption coefficient of PTS-polydiacetylene. The sign of n2 is negative and the magnitudes of nonlinearities are consistent with our previous reports on waveguide measurements.
