Paper Abstract

The intensity of two photon excited fluorescence (TPF) in highly scattering media generated by ultrashort laser pulses as a function of depth of focal point inside the media were measured for investigating the spatial location of TPF in scattering media. Scattering medium attenuates the intensity of incident beam. TPF signal decayed exponentially as the focal point was scanned into the medium. TPF was not confined in the focal region and had a wider distribution as the scattering strength of the medium increased resulting degradation of optical sectioning ability.
