Thermal Loading of Thin Metal Foils Used as Electron Beam Windows for a KRF Laser

Abstract

This paper presents experimental results of the foil temperature on the rep-rated electron beam pumped KrF laser during 50-shot bursts at 1 Hz and 5 Hz. The experiments demonstrate improved convective cooling of the foil during repetitive operation by confining the recirculating laser gas to flow along the hibachi foils.
