Abstract:

The title compound DMAHAS has been synthesized and characterized by ¹H-NMR spectra, IR spectra, and elemental analyses. Linear absorption, single-photon induced fluorescence and two-photon induced fluorescence are experimentally studied. This new dye has a moderate two-photon absorption cross-section of sigma

₂ = 0.91 × 10^-46 cm⁴ cdot

s/photon at 532 nm by using an open aperture Z-scan technique. When pumped with 800 nm laser irradiation, DMAHAS shows a strong two-photon induced blue fluorescence of 432 nm.

Keywords: Two-photon absorption; Z-scan; Optical properties; DMAHAS
