AbstractThe broad applicability of soft x-ray lasers to metallurgy, dense plasma diagnostics, nano/micro lithography, study of biological cells, and directed energy weapons has prompted a widespread search for lasing media. Gain has been demonstrated in plasma Droduced by large high Dower optical laser systems and pulse power Z pinch systems or in smaller capillary discharges which have a limited energy output. The resonant photo excitation of helium like A1 ions by helium like Si ions is proposed to generate soft x-rays at 45 A. A novel technique will be used to generate the required two component plasma using a pulse power discharge. A coaxial geometry will be used to efficiently pump the A1 lasant surrounding the Si pump. This geometry is expected to reduce requirements on the pulse power system making low cost soft x-ray lasers possible.
