Development, characterization and application of a high average power capillary discharge soft x-ray laser
MetadataShow full item record
A compact high repetition rate, high average power capillary discharge laser operating at a wavelength of 46.9 nm that is of the size of many widely utilized visible and UV lasers has been developed and characterized. Two significant differences from previously developed capillary discharge soft x-rays lasers, the use of ceramic capillaries rather than poly-acetal and significantly longer plasma columns of up to 36 cm, allowed for the generation of greatly increased output pulse energies and average power. Lasing at a repetition rate of 4 Hz and an average laser pulse energy of 0.88 mJ has been ...
