Outline

Laser is the ultimate light source created by mankind, and it has become an indispensable tool for our social life. In this laboratory, our main goal is to create an unexplored ultrafast laser by using the extreme nature of laser such as ultrashort pulse, super broadband, high power, and so on. Specifically, we are developing a high-power a few-cycle laser source, and using it to develop novel laser source with full coherence in the soft x-ray region and a pulse width of attosecond region. We extend the frontier of laser science through the development of novel laser sources.
