Title: X-ray free electron lasers and its applications
Abstract: Accelerator-based x-ray sources have revolutionized the field of x-ray science and technology, producing synchrotron radiation that to date have resulted in five Nobel prizes based on its use. With the advent of the first hard x-ray free-electron laser (XFEL) becoming operational in 2009 [1], peak brightness comparable to conventional lasers in the IR and optical regime has been achieved through self-amplified spontaneous emission (SASE) [2-3].
This talk will give an introduction to XFELs and the SASE process, discuss their recent development, and show examples of XFEL science applied to chemistry, biology, and molecular physics.
