摘要：

We study the possibility of amplified emission at wavelengths corresponding to transitions between multiphoton-pumped autoionizing states and initially unpopulated excited bound states of atomic or ionic systems. We test our ideas in He and Be2+ and find that amplification is possible, although the gain turns out to be extremely small for the cases studied so far. Variations of the amplification scheme that could lead to gain enhancement are discussed.
