| Research Abstract |
We have developed new optical microscopic imaging techniques which exploit the electronic and vibrational resonances in nonlinear-optical processes. Specifically, we demonstrated (a) the visualization of two-photon absorption resonances in red blood cells and plant petal cells based on stimulated parametric emission microscopy, and (b) background-free imaging of molecular vibrations based on stimulated Raman scattering microscopy.
