Experiments on soft x-ray laser development in a tabletop capillary discharge

摘要

The possibility of achieving soft x-ray amplification by collisional recombination in a capillary discharge plasma is being investigated. The results of the soft x-ray spectroscopy study of carbon capillary plasmas excited by a 40 kV, 108 ns FWHM discharge are discussed. The first spectra corresponding to a fast 25 ns FWHM, 600 kV discharge are also reported.
