title: Study of the two-photon excitation of photoinitiator in various solvents, and the two-photon polymerization process.
abstract: In this study, the two-photon absorption excited fluorescence of the photosensitizer 4,4'-Bis(diethylamino)benzophenonin in different solvents is investigated by using mode-locked Ti:sapphire excitation having a wavelength of 800 nm with pulse duration of 150 fs at the rate of 1 kHz. The fluorescence signals excited by wavelengths of 800 and 400 nm have been compared. Contribution of these cross-section measurements for the two-photon polymerization processes is also reported.
