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.
