Two-photon-induced fluorescence of biological markers based on optical fibers.
Optical fibers were used to induce fluorescence by means of two-photon absorption in fluorophores. The effect, studied in a solution of 4',6-diamidino-2-phenylindole, demonstrated that a single-mode fiber is a more efficient two-photon excitation source than a multimode fiber. This was shown with three different fibers.
