Two photon absorption of di-alkyl-amino-nitro-stilbene side chain polymer

The two photon absorption spectrum has been measured in the 780–1600 nm range for a di-alkyl-amino-nitro-stilbene side-chain polymer. A single two photon peak centered at 920 nm is observed with a peak two photon coefficient of 5.5 cm/GW. Bleaching via two photon absorption at this wavelength is inv...

Zusammenfassung:The two photon absorption spectrum has been measured in the 780–1600 nm range for a di-alkyl-amino-nitro-stilbene side-chain polymer. A single two photon peak centered at 920 nm is observed with a peak two photon coefficient of 5.5 cm/GW. Bleaching via two photon absorption at this wavelength is investigated by measuring a refractive index change after an intensive exposure.
