Abstract

Summary form only given. Transitions between the 4f/sup 2/5d configuration and the lower levels of the 4f/sup 3/ configuration in Nd/sup 3+/:YLF and Nd/sup 3+/:LaF/sub 3/ have been shown to be promising candidates for UV and VUV lasers. Hitherto these lasers have been pumped by exotic VUV F/sub 2/ lasers or VUV fluorescence from Kr/sub 2/* dimers excited by electron beams. In this paper, stepwise three-photon excitation of the 4f/sup 2/5d configuration in Nd/sup 3+/:YLF is investigated with nanosecond laser pulses.
