Ni-like x-ray lasers have been produced at wavelengths near to, and below the carbon K edge (43.76-A). Recent work has concentrated on the development of the Ni-like Ta amplifier at 44.83-A. Amplification occurs in a laser produced plasma created by irradiating a thin foil of Ta with two beams of the Nova laser. Up to 8 gainlengths have been demonstrated so far, with a gain coefficient of 3.2 cm-1 and a gain duration of 250 psec. The wavelength of 44.83-A is close to optimal for holographic imaging of live cells. It remains to optimize the coherent output power of the amplifier to use it as a source for future x-ray holography experiments.
