Phys. Rev. A 57, 4778–4783 (1998)Saturated operation of a transient collisional x-ray laserReceived 13 January 1998; published in the issue dated June 1998 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=1⃗1 transition at 30.15 nm. Small signal effective transient gain coefficients of g∼46 and ∼35cm-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 ∼5J. © 1998 The American Physical Society URL:
