| Outline of Final Research Achievements |
In study of a compact X-ray laser using laser plasma from solid rare-gas targets, we succeeded in enhancement of the plasma X-ray intensities. We confined spatially the laser-plasma using a tamper or a groove target to chill it rapidly and force ions to recombine and increase their emission intensities. As results, we achieved twice or three times enhancement of emission intensities around 50 nm in the solid Ar target comparing to a conventional plane target. We also observed such enhancement in solid Kr, Xe and N2 targets.
