I'd like to read the materials and methods section from the publication first though. Lets see what it actually took to achieve these results.

Imaging the nanoworld: Physicists use ultrafast lasers to create first tabletop x-ray device
Optics InfoBase: Optics Letters - Generation of hard x rays by femtosecond laser pulse interaction with solid targets in atmosphere
http://www.nims.go.jp/xray/ref/Vol.34No.4p621-626.pdf

Uses a Femtosecond IR laser pulsed into an atmosphere of He. Helium atoms when given a 1.6KeV pulse of energy respond in turn by producing a wide range of outputs including those into the 11.7nm range. Ultrahard UV. Technically Soft X-rays start around 10nm. 11.7nm is pretty darned close to Xray output. (I think I have oversimplified the process somewhat), but you get the idea.

There you have it. I bet you the laser they're using is a Femtosecond Sapphire as well.
