چکیده انگلیسی
Three-photon pumped frequency-upconversion fluorescence and nonlinear transmission properties of tris-[4-(2-{4-[5-(4-tert-butyl-phenyl)-[1,3,4]oxadiazol-2-yl]-phenyl}-vinyl)-phenyl]-amine (TPAD3) are studied using a Ti:Sapphire oscillator-amplifier system associated with an optical-parametric amplifier, which could specifically provide â¼80Â fs duration and 1175-1300Â nm laser pulses for three-photon excitation. The dye shows very efficient three-photon pumped frequency-upconversion fluorescence and three-photon absorption at wavelengths from 1175Â nm to 1300Â nm. In our study, the beam intensity distribution is also taken into account. For the first time we give the analytical solution to nonlinear transmission of a three-photon absorption process when the incident beam has a Gaussian transverse spatial profile.
