我们已经证明了真空紫外（VUV）Kr(2)*激光振荡是通过使用紧凑的放电装置实现高压Kr的稳定自持放电的结果。使用高达 10 atm 的纯 Kr 可获得辉光放电。当充电电压超过一定值时，以147.8 nm为中心的VUV发射强度突然增加。除了这种阈值行为之外，当充电电压增加时，还观察到相当大的光谱变窄（4.0±0.4 nm）。 148 nm处的最大输出能量为150muJ。增益系数估计为1.1%cm (-1) 。
We have demonstrated vacuum-ultraviolet (VUV) Kr(2) * laser oscillation as a result of the realization of a stable self-sustained discharge of high-pressure Kr by use of a compact discharge device. Glow discharge was obtained with as much as 10 atm of pure Kr. The VUV emission intensity centered at 147.8 nm abruptly increased when the charging voltage exceeded a certain value. In addition to this threshold behavior, considerable spectral narrowing (4.0?0.4 nm) was observed when the charging voltage increased. The maximum output energy at 148 nm was 150muJ . The gain coefficient was estimated to be 1.1% cm (-1) .
