Abstract
We have measured UV fluorescence excited through two-photon absorption from native chicken tissue, using 600-nm, 500-fs pulses from a R6G dy e laser. The observed emission signal was found to depend quadraticall y on the excitation intensity. The two-photon excitation-induced fluor escence spectrum is attributed to tryptophan residues in proteins.
