We report the observation of high-gain lasing in laser-heated exploding-foil Ag targets at pump irradiances 6×1014 W/cm2. The measured gain coefficients on the dominant Ne-like J=21 transitions are determined to be 9.41.5 cm-1 for (2p3/2)3p3/2(2p3/2)3s at 9.9365 nm and 6.4-1.5+2.0 cm-1 for (2p1/2)3p3/2(2p1/2)3s 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 J=01 transition at 8.1563 nm, the shortest wavelength yet observed to our knowledge for a Ne-like x-ray laser.
