Abstract
The two photon absorption spectrum has been measured in the 780-1600 n m range for a di-alkyl-amino-nitro-stilbene side-chain polymer. A sing le two photon peak centered at 920 nm is observed with a peak two phot on coefficient of 5.5 cm/GW Bleaching via two photon absorption at thi s wavelength is investigated by measuring a refractive index change af ter an intensive exposure.
