Preferred Label : two-photon excitation;
IUPAC definition : Excitation resulting from successive or simultaneous absorption of two photons by
an atom or molecular entity. This term is used for successive absorption only if some
of the excitation energy of the first photon remains in the atom or molecular entity
before absorption of the second photon. The simultaneous two-photon absorption can
also be called biphotonic excitation.;
