An atomic inner-shell laser pumped with an x-ray free-electron laser
Focusing an x-ray free electron laser (XFEL) pulse into a gas target, a plasma of transiently core excited ions can be created within a few femtoseconds, building a pathway to an inner-shell keV atomic x-ray laser. Varying the XFEL parameters, a wide variety of pulse structures can be created with comparable peak-intensities to XFELs: isolated pulses of sub-femtosecond duration, trains of pulse...
متن کاملFeasibility considerations of a soft-x-ray distributed feedback laser pumped by an x-ray free electron laser
We discuss the feasibility of a soft-x-ray distributed feedback laser (DFL) pumped by an xray free electron laser (X-FEL). The DFL under consideration is a Mg/SiC bi-layered Bragg reflector pumped by a single X-FEL bunch at 57.4 eV, stimulating the Mg L2,3 emission at 49 eV corresponding to the 3s-3d -> 2p1/2,3/2 transition. Based on a model developed by Yariv and Yeh and an extended coupled-wa...
متن کاملDeep inner-shell multiphoton ionization by intense x-ray free-electron laser pulses.
We have investigated multiphoton multiple ionization dynamics of xenon atoms using a new x-ray free-electron laser facility, SPring-8 Angstrom Compact free electron LAser (SACLA) in Japan, and identified that Xe(n+) with n up to 26 is produced at a photon energy of 5.5 keV. The observed high charge states (n≥24) are produced via five-photon absorption, evidencing the occurrence of multiphoton a...
متن کاملDesign of an X-ray Free Electron Laser Undulator
An undulator designed to be used for an x-ray free electron laser has to meet a set of stringent requirements. With no optical cavity, an x-ray FEL operates in the single pass Self Amplfied Spontaneous Emission (SASE) mode; an electron macropulse is microbunched by an undulator and the radiation it creates. The microbunched pulse emits spontaneous radiation and coherent FEL radiation, whose pow...
متن کاملPair creation and an x-ray free electron laser.
Using a quantum kinetic equation we study the possibility that focused beams at proposed x-ray free electron laser facilities can initiate spontaneous electron-positron pair production from the QED vacuum. Under conditions reckoned achievable at planned facilities, repeated cycles of particle creation and annihilation will take place in tune with the laser frequency. The peak particle number de...
