• We report the observation of high-gain lasing in laser-heated exploding-foil Ag targets at pump irradiances {ge}6{times}10{sup 14} W/cm{sup 2}. The measured gain coefficients on the dominant Ne-like {ital J}=2{r arrow}1 transitions are determined to be 9.4{plus minus}1.5 cm{sup {minus}1} for (2{ital p}{sub 3/2})3{ital p}{sub 3/2}{r arrow}(2{ital p}{sub 3/2})3{ital s} at 9.9365 nm and 6.4{sub {minus}1.5}{sup +2.0} cm{sup {minus}1} for (2{ital p}{sub 1/2})3{ital p}{sub 3/2}{r arrow}(2{ital p}{sub 1/2})3{ital s} at 10.0377 nm. These are the highest gain coefficients yet observed to our knowledge for any short-wavelength laser. Gain is observed on three other Ne-like lines including a {ital J}=0{r arrow}1 transition at 8.1563 nm, the shortest wavelength yet observed to our knowledge for a Ne-like x-ray laser.
