Advancing X-Ray Lasers and Intense X-Ray Sources with Ultrashort-Pulse, High-Intensity Lasers
摘要
The collisional-excitation X-ray laser (XRL) has made remarkable progress among various XRL schemes, although intense lasing in the water-window region remains to be demonstrated. In contrast, other schemes such as recombination, photo-pumping, and inner shell ionization XRLs, which have possibilities for lasing in the water-window region, have yet room for exploration. Considering the rapid progress of ultrashort-pulse, high-power lasers in recent years, we will review the XRL and intense x-ray generation research which could be explored with these advanced lasers. After a brief review of the XRL research at ILE and KIPS, we consider several XRL schemes and X-ray sources which are attractive for exploration to the water-window and shorter wavelength regions. In the final section, recent status of the ultrashort, high-power laser development is briefly reviewed.
