    Abstract

    Experimental evidence is presented showing that when two linearly polarized beams intersect and cause two-photon absorption in a dye-doped solution, the strength of the resulting visible emission strongly depends on the angle between the beams' polarizations. The two-photon absorption strength itself is shown to depend only on the electronic transition accessed, in agreement with previously reported studies. However, for three-dimensional display applications it is the visible emission strength that the viewer perceives that is of interest. Four different dyes in solution were used (coumarin 7 , rhodamine B, naphthofluorescein, and fluorescein) and several parameters that affect the polarization dependence of the visible signal strength were identified, including the excited state attained, the relative irradiance of each pump beam, and the solvent viscosity.
