Saturation of a low pump energy x-ray laser utilizing a transient inversion mechanism on the 3 p-3s transition at 32.63 nm in Ne-like Ti has been demonstrated. A close to saturation amplification was simultaneously achieved for the 3d-3p, Jϭ1→1 transition at 30.15 nm. Small signal effective transient gain coefficients of gϳ46 and ϳ35 cm Ϫ1 and gain-length products of 16.7 and 16.9 for these lines were obtained. Experiments demonstrate that it is possible to achieve saturated laser action in a transient regime with Ne-like Ti for a pump energy as low as ϳ5 J.
