Abstract

The influence of uncertainty in intensity of radiation of individual laser pulses on probabilities of multiphoton ionization/photodetachment is analyzed quantitatively. Both multiphoton (using an example of an F⁻ anion) and tunnel regimes are studied. It is demonstrated that intensity fluctuations substantially change probabilities of the discussed processes. As to the tunnel regime, the role of fluctuations is negligibly small not only in the region of saturation but also far from it in this case.

激光脉冲辐射的有效强度对多光子过程速率的影响

摘要

定量分析了单个激光脉冲的辐射强度的不确定性对多光子电离/光解离概率的影响。两个多光子（使用F的一个例子^-阴离子）和隧道机制进行了研究。证明强度波动实质上改变了所讨论过程的概率。至于隧道状况，波动的作用不仅在饱和区很小，而且在这种情况下也远不算大。
