Our paper, Efficient non-degenerate two-photon excitation for fluorescence microscopy, is an Optics Express Editor's Pick! Fluorescence of all tested small molecules & fluorescent proteins was increased with non-degenerate 2-photon excitation or 2 specific wavelengths. Collaboration between researchers at UCSD, Boston University, The George Washington University, & Harvard.
