"Laboratory-size multi-keV x-ray laser:
Design and construction
"



Dr. Peter M. Rentzepis
University of California, Irvine

ABSTRACT 

The design and construction of hard, keV, x-ray lasers has been elusive for the past 50 years, or so, owing to the absence of: a) highly reflecting crystals at the Bragg angle of the x-ray fluorescence wavelength that are necessary for the construction of the resonator. b) The lack of gain media that meet the resonator parameters and exhibit high fluorescence quantum yield and low Auger efficiency.These constrains coupled with the ultrafast, fs, k-hole decay rate, impose stringent restrictions on the medium pumping source that so far have been very difficult to overcome.

We shall present the design and successful construction of keV x-ray laser resonators, and discuss the characteristic properties and needed for the gain media and pumping sources. We shall also propose possible means for the design and construction of such x-ray laser systems and describe their visualized physical arrangement of the components and their operation.
