Abstract

We report on the generation of tunable nanosecond pulsed VUV radiation near 120 nm using difference-frequency mixing in H(2). Our scheme uses two dye lasers, one fixed at 606 nm and the other tunable in the red. These convenient wavelengths simplify the metrology needed for accurate VUV laser spectroscopy. Efficient VUV generation is attained with modest Nd:YAG pump laser energies (approximately 160 mJ at 532 nm), making the scheme attractive even when narrow bandwidths are not essential.

摘要

我们报告了利用氢气中的差频混合产生近120纳米可调谐纳秒脉冲真空紫外辐射的情况。我们的方案使用两台染料激光器，一台固定在606纳米，另一台在红光波段可调谐。这些便利的波长简化了精确真空紫外激光光谱所需的计量学。用适度的钕：钇铝石榴石泵浦激光能量（532纳米处约160毫焦）就能实现高效的真空紫外产生，即使在不需要窄带宽的情况下，该方案也很有吸引力。
