In this work, to provide an unified description of the light reflections from underdense and overdense plasmas, we develop an analytic model describing the reflection amplitude by using the path-integral approach. By integrating all the reflection paths propagating back to the vacuum, we obtain analytic solution of the reflection amplitude. Our model well reproduces results of 1-dimensional particle in cell simulation. In the presentation, we explain the physical meaning of our analytic model in more details and the prospect of our approach.
