two-photon fluorescence

This results from the simultaneous absorption of two photons, each having half the energy needed for excitation and requiring a high spatial and temporal concentration of photons. The ensuing confocal effect confines the excitation to the plane of focus. The technique provides longer observation times for live cell studies.
