Welcome to the Attosecond Science Laboratory at IBS - GIST

"1 as = 0.000000000000000001 sec"

Attosecond science is a branch of strong field physics that investigates ultrafast phenomena in nature. An attosecond (1 as = 10-18 as) is a characteristic time scale for the description of electron dynamics. The electron plays a key role in many phenomena: it determines molecular structure and bond formation; it relays information and is used in calculations in electronic devices, and it absorbs and emits radiation. The control of chemical processes, revolutions in communications and computing, and generation of novel light sources are areas of research that benefit from the study of ultrafast electron dynamics. The goal of attosecond science is to understand and manipulate ultrafast electron dynamics in a variety of materials such as atoms, molecules, and solids with the purpose of future applications.


Attosecond science laboratory (lead by Group Leader Prof. Kyung Taec Kim) is a sub research group of the Center for relativisitic laser science (lead by Director Chang Hee Nam). The following areas are the research subject interested.

  • Attosecond pulse generation and characterization
  • Femtosecond laser technology
  • Atomic and molecular attosecond physics
  • Strong field plasmonics
  • High energy physics
  • Attosecond science in the relativistic regime
