Proceedings Paper

From multi-photon absorption and stimulated emission to forbidden S0→T1 transition (Conference Presentation)

Paper Abstract

We will overview our initial developments of two, three, and four-photon excitation that started in early nineties with parallel developments in two-color two photon excitation to applications of light quenching (light stimulated emission) as a process to shape the excited state population. We will summarize our basic spectroscopy and time-resolved work in a cuvette system to total internal reflection applications. We will present more recent application of multi-photon processes in the case of metal enhanced fluorescence (MAF) and surface plasmons coupled emission (SPCE). Finally we will present the most recent observation of directly excited phosphorescence (S0→T1 excitation) and discuss potential applications in protein studies and cellular imaging.
