โœฆ Synopsis

Fluorescence emission after two-photon excitation at 532 nm by means of a Nd : YAG laser is observed in apohemoglobm, hemoglobm,albumin and tryptophan at room temperature. The experimental results show that the fluorescence of these proteins originates from tryptophan residues_ No fluorescenar of a biphotonic nature could be detected from lysozyme and tyrosine.

We observed two-color two-photon (2C2P) excitation of indole upon simultaneous illumination at 380 and 760 nm with picosecond pulses from a cavity-dumped dye laser. The emission spectrum of indole with 2C2P excitation was the same as observed for one-photon excitation with an equivalent energy of 25
