Fluorescence optical microscopy is critical for revealing structures and dynamics in complex chemical and biological systems. However, its power to resolve complexity is restricted by the limited number of chromophores that can be deployed in imaging, due to overlapping fluorescence spectra in the visible wavelengths. Using femtosecond nonlinear interactions between infrared (IR) and visible beams on matters, we can register multi-dimensional information into photoluminescence images, distinguishing chromophores apart even if they have nearly the same emission color.
