Philip Kaatz and David P. Shelton, "Two-photon fluorescence cross-section measurements calibrated with hyper-Rayleigh scattering," J. Opt. Soc. Am. B 16, 998-1006 (1999)
The intensity of two-photon-excited fluorescence measured relative to the intensity of hyper-Rayleigh scattering in the same apparatus was used to determine the two-photon-excited fluorescence cross sections of the xanthene dyes Rhodamine B, Rhodamine 6G, and Fluorescein. The measured cross sections at are
and for the three dyes, respectively. The two-photon-excited fluorescence cross section of Rhodamine B was also calibrated with one-photon-excited fluorescence in this apparatus. The result, is in reasonable agreement with the result calibrated by hyper-Rayleigh scattering. The results for Rhodamine B are 1.5–6 times smaller than previous results calibrated by one-photon-excited fluorescence.
