我们提出了一种新的x射线激光机制，使用辐射从最强的3d？在光学厚等离子体中的2p类Ne共振线将布居从类Ne基态辐射驱动到3d态，然后激光到两个3p态。3p态与附近的3s和3d态的碰撞混合减少了较低的激光态。建模这种机制在氖类氩，并在实验中，我们观察到一个潜在的3D？类氖氩中45.1nm的3p激光跃迁。
We propose a new x-ray laser mechanism that uses radiation from the strongest 3d ? 2p Ne-like resonance line in an optically thick plasma to radiatively drive population from the Ne-like ground state to the 3d state, which then lases to two 3p states. Collisional mixing of the 3p states with nearby 3s and 3d states depopulates the lower laser states. Modeling is presented for this mechanism in Ne-like Ar, and in experiments we observe one potential 3d ? 3p lasing transition at 45.1 nm in Ne-like Ar.
