Abstract

Two-photon absorption properties of rhodamine 6G in ethanol and PMMA were researched applying femtosecond pulses. The two-photon absorption cross section of rhodamine 6G in PMMA was found much larger than that in ethanol. Fluorescence properties of this kind of dye in ethanol and PMMA were also researched. The detuning of two-photon absorption for rhodamine 6G dissolved in PMMA is diminished compared with that in ethanol when excited at 800 nm. And the increase of two-photon absorption cross section of rhodamine 6G in PMMA was attributed mainly to the diminishing of detuning.
