The two-photon absorption cross-sections and excited-state absorption cross-sections of the dyes rhodamine 6G, methylene blue and fuchsin dissolved in methanol, and of the dyes safranine T, 1,3,3,1′,3′,3′-hexamethylindocarbocyanine iodide (HMICI) and 1,3,1′,3′-tetramethyl-2,2′-dioxopyrimidi-6,6′-carbocyanine hydrogen sulphate (PYC) dissolved in hexafluoroisopropanol (HFIP) are determined. The excitation is achieved with picosecond light pulses of a passively mode-locked Nd-glass laser (λL = 1.054μm). The influence of amplified spontaneous emission on the two-photon absorption dynamics is analysed.
