Hamburg Photon Science Colloquium | Progress of inner-shell ionized hard X-ray laser pumped by XFEL

by Hitoki Yoneda (Institute for Laser Science, University of Electro-Communicatons,Tokyo, Japan)


The intense hard X-rays from XFEL can create high excitation density conditions of a specific ionization state of the atoms in solid materials. About 20% of the atoms in a solid metal can be ionized in a very short time interval (<10fs) at XFEL intensity of1020W/cm2. This well-ordered nonequilibrium condition is suitable for new hard-ray laser medium. Recently, we demonstrate a new type of mode-selective hard-ray lasers based on a distribution feedback Bragg (DFB) scheme.


IMPORTANT INFORMATION: The Hamburg Photon Science Colloquium will be put on video using the recording function of zoom.
