We present measurements of two-photon excitation (TPE) spectra of various fluorescent proteins with nonlinear Fourier-transform spectroscopy. By using an ultrabroadband laser pulse with a spectrum ranging from 700 to 1100 nm, the absolute TPE spectra of six typical fluorescent proteins (SeBFP, Sapphire, eGFP, eCFP, Venus, DsRed) were measured with high spectral resolution.
