Longitudinal pumping by an ellipsoidal reflector for short-wavelength lasers

Abstract

We have designed and tested an ellipsoidal reflector to pump short-wavelength lasers by soft x-ray radiation from laser produced plasma. A gaseous medium supplied by a slit nozzle was pumped longitudinally along the optical axis in the region of the second focus. Soft x-ray absorption and VUV emission of gaseous medium have been investigated.
