N2 - Herein, we report the study of the three-photon absorption cross-section dependence on solvents parameters for a highly conjugated organic dye, 2, 2′ -(4, 4′ -(1E, 1′ E)-2, 2′ -(9,9-didecyl-9H-fluorene- 2,7-diyl) bis(ethene-2,1-diyl)bis(4,1-phenylene))dibenzo[d]thiazole (A - π - π - π - A). The three-photon absorption cross-section was measured for this organic dye in solution in four different solvents with polarity function, Δf between 0.162 and 0.247. The experiments show how the solvent's reorientation of the electrons and polarity contribute to the 3PA cross-section. Multiphoton-absorption experiments of A- π - π - π -A in all four different solvents were performed with a tunable OPG pumped by a 25 picosecond Nd-YAG laser.
