| Abstract: | Trans‐4‐(N, N'‐dimethyl amino)‐4′‐(N‐hydroxyethyl‐N'‐ethyl amino) stilbene (DMAHAS) has been synthesized and characterized by 1H NMR spectra, ER spectra and elemental analysis. Linear absorption, single‐photon induced fluorescence and two‐photon induced fluorescence were experimentally studied. This new dye has a moderate two‐photon absorption cross‐section of σ 2 = 0.91 × 10–46 cm4 · s/photon at 532 nm by using an open aperture Z‐scan technique. The result indicates that DMAHAS shows a strong two‐photon induced blue fluorescence of 432 nm when pumped with 800 nm laser irradiation. |
