What am I doing?

At SIOM (Shanghai Institute of Optics and Fine Mechanics, CAS), I lead a small group of young researchers and students, researching on nonlinear effects in optical fiber and laser technology, and developing new kind of lasers with specifications not met before for scientific applications, including laser guide star for astronomy, cooling of atoms and solids, and LIDARs etc.

At other times, I watch my daughters grow, and read some books hopefully.
