| 摘 要： | 利用Ｗｉｎｇｅｒ－Ｗｅｉｓｓｋｏｐｆ近似研究了光致离化系统中的暗态效应，在双模量子化光场的驱动下，三个束缚态形成一个暗态，即使在ｔ→∞的条件下，原子在该暗态上也能保持一定的居数，还给出了光子数对原子在束缚态年的占居数的影响。

| Abstract: | Using the Wigner Weisskopf approximation, the dark state effect in a Raman type photoionization system is studied. Driven by two quantum fields, a dark state is formed from three discrete states of the system, which does bot decay to the contunuum for a long period. The effect of photon number on the poulation trapping is discussed. |

| Keywords: | photoionization system dark state population trapping |
