    • Intrinsic Nonlinear Microscopy: From Neuronal Firing to Historical Artwork 

      Samineni, Prathyush (2012)
      Imaging based on nonlinear processes takes advantage of the localized excitation to achieve high spatial resolution, optical sectioning, and deeper penetration in highly scattering media. However, the use of nonlinear contrast ...
    • Measurements of nonlinear refractive index in scattering media. 

      Samineni, Prathyush; Perret, Zachary; Warren, Warren S; Fischer, Martin C (Opt Express, 2010-06-07)
      We have recently developed a spectral re-shaping technique to simultaneously measure nonlinear refractive index and nonlinear absorption. In this technique, the information about the nonlinearities is encoded in the frequency ...
