固体或液体的稀有气体（RG）的受激发射的可行性被认为是，特别是在由放电泵浦的氙气的情况下。分析了在液体或晶体中建立均匀放电的可能性，以这种方式，放电能量的大部分用于激发RG2激子。应该可以达到30 kW的激光输出功率，脉冲持续时间长达1 ms，效率应高达30%。所获得的估计和对已发表数据的分析表明，用凝聚的氙、氪或氩作为活性介质（分别在172、145和128 nm波长处发射）来构造有效的准分子激光器不仅在原则上是可能的，而且在实践中应该是可以实现的。
The feasibility of stimulated emission from solid or liquid rare gases (RG) is considered, particularly in the case of xenon pumped by an electric discharge. An analysis is made of the possibility of establishing a homogeneous electric discharge in a liquid or a crystal in such a way that the bulk of the discharge energy is used to excite RG2 excitons. It should be possible to reach a laser output power of 30 kW in the form of pulses up to 1 ms in duration and the efficiency should be up to 30%. The estimates obtained and an analysis of the published data show that the construction of efficient excimer lasers with condensed xenon, krypton, or argon as the active medium (emitting at wavelengths of 172, 145, and 128 nm, respectively) is not only possible in principle, but should be realisable in practice.
