Foil cooling for rep-rated electron beam pumped KrF lasers
In rep-rated electron beam pumped lasers the foil
separating the vacuum diode from the laser gas is subject to repeated
heating due to partial beam stopping. Three cooling methods are examined for
the Electra KrF laser at the Naval Research Laboratory (NRL). Foil
temperature measurements for convective cooling by the recirculating laser
gas and by spray mist cooling are reported, along with estimates for thermal
conductive foil cooling to the hibachi ribs. Issues on the application of
each of these approaches to laser drivers in a fusion power plant are noted
