引入了一个简单的激光诱导负离子光脱离模型，结合Wigner幂定律，讨论了强激发激光场在阈值附近的非摄动效应。作者发现，正如预期的那样，这一阈值可能会被抹去或轻微移动。更有趣的是在阈值附近观察到幂律（t-3）和其他偏离束缚电子概率指数衰减的可能性。
Introduces a simple model of laser-induced negative ion photodetachment, incorporating the Wigner power law, in order to discuss non-perturbatively the effects of strong exciting laser fields near to threshold. The authors find that the threshold can be smeared out and shifted slightly, as might be expected. More interesting is the possibility of observing power law (t-3) and other deviations from the exponential decay of bound electron probability near to threshold.
