Ultrafast laser science and technology has deeply impacted our understanding of the nature and the ability of transforming the world. By concentrating the light energy into a very short time scale of picosecond (10^-12 s), femtosecond (10^-15 s) and even attosecond (10^-18 s), ultrafast laser pulse could play as the “fastest camera” to record the motion dynamic of molecules, atoms and electrons, etc. The highest light intensity product by ultrafast laser pulse has exceeded 10^22 W/cm^2 and is expected to reach 10^24 W/cm^2 (10^25 times more intense than the sunlight striking Earth) in a few years by building a 100 PW (10^17 W) laser system in SIOM, Shanghai. The ultrafast laser is so powerful that it has the ability to transform the material at the sub-atomic scale, being the “most accurate knife” nowadays. Since 1995, ultrafast laser science and technology have been awarded Nobel prizes in Physics or Chemistry four times.
Working at the forefront of ultrafast laser science and technology, our group is devoted to studying the fundamental physics of the interaction of ultrafast laser pulse with matters, to developing cutting edge spectroscopic and imaging techniques to fulfill the applications in atmospheric pollution detection, non-destructive inspection and bio-medical examination.
