Abstract

Concerning the extreme ultraviolet lasing in the laser-produced plasma, He -like Al scheme is atractive because the wavewlength of He-like 3-2 transitions are shorter than any other transition ever done, and very close to the water window. This scheme is expected to give a large population inversion caused by the rapid decaying of the n=2 level, and the great feed to the n=3 levels by the cascade radiative transitions and two electron transitions through the autoionized states.
