The wavefront of a λ=18.9 nm soft x-ray beam from an injection-seeded plasma amplifier was measured using a Hartmann sensor. An optical quality superior to that of the seed, up to λ/7 rms, was obtained.
The linewidth of an injection-seeded 18.9nm molybdenum soft x-ray laser (SXRL) was measured to be significantly wider than seeded optical field ionization SXRLs that use gaseous targets, an advantage for the development of sub-picosecond SXRLs.
We review recent progress in the development of table-top soft x-ray lasers that includes the demonstration of a gain-saturated λ = 10.9 nm laser, and the first demonstration of an all-diode-pumped soft x-ray laser.
We report a 10.9nm gain-saturated table-top soft x-ray laser operating at 1 Hz repetition rate. With average power of 1 microwatt and pulse energy up to ~ 2 microjoules this laser extends the ability to conduct table-top laser experiments to a shorter wavelength.

Phase-coherent soft x-ray laser pulses of 1.13 plusmn 0.47 ps duration were generated by injection-seeding a solid-target Ne-like Ti plasma amplifier with high harmonic pulses. This is the shortest pulse duration reported to date from a table-top soft x-ray laser amplifier.
