Recent experimental results of Al XI x-ray lasing in recombining plasmas are described. ASE{close_quote}s of two Li-like Al lines (105.7 A and 154.7 A) were observed using a pulse-train laser with only 2.3 J/cm pumping energy. Gain coefficient of 105.7 A was improved up to over 4 cm{sup {minus}1} when laser intensity of the second half of a pulse-train laser was reduced to 25{percent} of the first one. The time duration of the gain was about 1 ns. Also a experiment on double-pass amplification of Al{sup 10+} 154.7 A 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. {copyright} {ital 1996 American Institute of Physics.}
