Chapter Ⅱ reviews the general theory of Stark effect from our point of view. We describe three kinds of theoretical approaches about the treatment of ac Stark effect, which are time-dependent perturbation theory in semiclassical argument; Rabi methods in the semiclassical theory; dressedstate approach---quantum treatment of the light field. We also compare and discuss their scope of application.
