Abstract : A program was conducted to continue development of a potassium- rubidium arclamp for laser pumping. Significant progress was made. Improved lamp bake-out, improved filling procedures and incorporation of an internal uranium getter prevented attack of the polished sapphire lamp envelope by the potassium vapor. A new, single envelope, air compatible lamp with nickel endcaps and novel brazed endseals was successfully tested. Dramatic improvement in laser pumping efficiency was achieved by substituting xenon starting gas for argon. Difficulties were encountered in fabricating an alternative lamp with double endcaps (protected end seals). This prompted a development effort to improve joining technology for this lamp. Encouraging results were obtained with a fused silicide oxidation protective coating for niobium endcap lamps. The best life test result on nickel endcap lamps was 85 operating cycles and 464 hours. Work is continuing on a subsequent contract.
