We are a multidisciplinary group that mainly plays with ultrashort lasers and microscopes. With nonlinear optical spectroscopy, we could peek into the dimensions that are not accessible by linear optics, and gain information in the ultrafast time domain (fs-ps) as well as the spectral domain. These information tell us stories of how electrons, phonons and molecules behave under the illumination of photons. What’s more, the unusual optical characteristics of molecules could be applied for medical diagnosis when combined with microscopy techniques.

Our current research projects involve:
1.Developing microscopy techniques for label-free imaging, including stimulated Raman scattering (SRS), pump-probe, second harmonic generation (SHG) and two-photon excited fluorescence (TPEF).
2.Biomedical imaging with these microscopy techniques.
3.Spatial-temporal behavior of carriers in novel 2D materials.
4.Nonlinear optical properties of quantum materials.
5.Spectroscopies of molecules with particularly interesting properties, such as chiral molecules and surface enhanced molecules.
