Saturation of a low pump energy x-ray laser utilizing a transient inversion mechanism on the 3p-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, J=1-->1 transition at 30.15 nm. Small signal effective transient gain coefficients of g similar to 46 and similar to 35 cm(-1) 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 similar to 5 J.
