| Abstract: | We show that phase-sensitive detection of spectral hole refilling can yield information about self-phase modulation and two-photon absorption coefficients. We expect that, when applied to tissue microscopy, this technique will allow the study of endogenous molecular markers beneath the surface, even if those markers are nonfluorescent. |
