Keywords:X-ray free-electron laser, dynamics

X-ray free-electron lasers (XFELs) provide brilliant X-ray pulses with femtosecond duration and are utilized to track dynamics, which is difficult to capture using synchrotron radiation. In the femtosecond time domain, one can achieve "molecular movie"^1-3 with an atomic spatio-temporal resolution by combining XFEL and synchronized optical laser pulses. On the other hand, in the nanosecond time domain, XFELs are utilized to observe irreversible dynamic processes^4,5 with the single-shot measurement scheme that can not be performed with synchrotron radiation.
In this presentation, I will talk XFEL properties and research examples at SACLA to discuss the XFEL potentials in Earth and planetary science.
