摘要
本文详细地讨论了三能级系统多光子过程的光强指数。给出了光强指数随激光光强变化关系图。并用此图对光强指数的过渡区进行了理论分析。结果表明，过渡区能向我们提供关于多光子过程的许多信息。同时，我们还用一些数值模拟计算，与文献[9]结果的比较，以及我们的实验结果来表明分析的合理性。
Laser power index in multiphoton processes is discussed in detail for the simple three-level system. The figure of laser power index changing with the laser power is given.The transition region of laser power index is theoretically analyzed. The result shows that the transition region contains much information on multiphoton processes. The validity of our analysis is demonstrated by means of some numerical and experimental results.
