Abstract

ASEs of two Li-like Al lines (105.7 angstrom and 154.7 angstrom) were observed using a pulse-train laser with only 2.3 J/cm pumping energy. Gain coefficient of 105.7 angstrom was improved up to over 4 cm^-1 when laser intensity of the second half of a pulse- train laser was reduced to 25% of the first one. The time duration of the gain was about 1 ns within the 3 ns total time duration of pulse-train laser. Also an experiment on double-pass amplification of Al¹⁰⁺ 154.7 Angstrom line was carried out by using an x-ray multi- layer mirror and increase of the line intensity by a factor of 4.4 was observed.
