| 摘 要： | A new configuration of double-pulse laser heating is proposed for x-ray laser research. The double-pulse consisting of a main pulse (first) and a "tailed" pulse (second) with less energy can increase the fraction of highly ionized states efficiently. Population inversion in He-like Al ions between the n=3 and 2 levels has been found with such a novel laser heating configuration. The possible physical mechanisms are discussed.
