Abstract

We review the progress in the development of ultrashort- wavelength lasers based on discharge excitation. The observation of large soft x-ray amplification in Ne-like Ar at 46.9 nm in a capillary discharge created plasma [Phys. Rev. Lett. 77, 1476, (1996)] have opened a new path for the development of compact and practical soft x-ray lasers. These results have shattered the earlier perception that discharge- created plasmas are insufficiently stable and uniform for soft x-ray lasing. We report results of a detailed characterization of the capillary discharge Ne-like Ar laser, that include near-field and far-field images of the laser output and the measurement of its spatial coherence. The recent demonstration of lasing in Ne-like S at 60.8 nm in material ablated from a solid target by a discharge is also discussed.
