Abstract
The effect of phase fluctuations of a laser on the atomic reflection of evanescent light is investigated. This effect is one of the main factors that limit the performance of the atomic mirror action obstructing the ultimate goal of near-perfect coherent reflection process. It is concluded that this effect plays a significant role hence should be incorporated in the treatment of quantum dynamics. By operating at low intensities, that could be achieved by the addition of thin metallic layer, these effects can only be minimized. Based on these considerations, the atomic mirror action is determined.
