Population Inversion X-ray Laser Oscillator at LCLS and LCLS-II | |
|
||
| The advancement of X-ray Free Electron Lasers (XFELs) has created revolutionary new research opportunities, owing to their high peak and average power, transverse coherence, and short pulse duration. Despite their remarkable capabilities, XFEL pulses lack longitudinal coherence and are not transform-limited, which limits their utilization, e.g. in quantum optics and precision interferometry. We explore the development of coherent, transform-limited pulses through alternative strategies, namely, X-ray lasers based on population inversion. We propose a novel approach relying on the principle of stimulated emission in the hard X-ray regime, using the XFEL as a pump. We will specifically discuss the case of the X-ray Laser Oscillator (XLO) at the LCLS copper linac and the planed LCLS-II-HE. Our recent work has shown the feasibility and performance characteristics of these systems, which can operate over a broad wavelength range from 5 to 12 keV. Future applications at LCLS-II-HE might allow for transform-limited XLO pulses with repetition rates up to tens of kHz. We show that XLO is experimentally feasible and discuss its projected performance and photon pulse properties operating at the Copper K-alpha1 line. Finally, we discuss possible first experiments with XLO. | ||
