Paper Abstract

We describe the application of two-photon processes and fluorescence to 3D optical data storage. We also report the results of two-photon absorption (TPA) cross section measurement of several organic molecules in solution. The data show that the nonlinear transmission method without consideration of other nonlinear effects results in erroneous values for the TPA cross sections. We also find that the cross sections measured by excited state methods, namely two-photon induced fluorescence and a new excited state method, which is based on transient absorption following two-photon excitation, are in good agreement with the accepted values. Therefore one needs to be cognizant of these facts when using the transmission method.
