Two-step excitation of fluorescent proteins with real intermediary states
J. David Wong-Campos, Dalia P. Ornelas-Huerta, Mackenzie Dion
We demonstrate sequential two-photon fluorescence microscopy using forbidden state transitions. Nonlinear red excitation leads to green fluorescence in live cells expressing eYFP,…

Multiphoton fluorescence excitation with real intermediary states
J. David Wong-Campos, Mackenzie Dion
We demonstrate fluorescence generation through a sequential multiphoton process with real intermediary states. Our findings suggest new directions for optical control of previously…
