ABSTRACT:
A vacuum ultraviolet and x-ray light source based on spontaneous anti-Stokes scattering from atomic population stored in a metastable level is described. The source has a maximum brightness, attained as the media approaches two-photon opacity, equal to that of a blackbody at a Boltzmann temperature characteristic of the population of the metastable level. The source may have high resolution, picosecond time scale, and on a pulsed basis is brighter than other laboratory vacuum ultraviolet light sources. Short wavelength lasers pumped by said source are also described. The lasing atomic species can be separate from or combined in the same envelope with the light source atomic species. Use of the source for spectrographic applications is also described.
