Interference stabilization of Rydberg atoms in a strong laser field and phase locking of an array of cavities: Common properties of the phenomena

A description of the common properties for different phenomena is presented: interference stabilization of Rydberg atoms in a strong electromagnetic field and phase locking of an array of cavities. A comparison of master equations is held for the discussed effects. Analytical expressions for basic parameters of the problems involved are used for quantitative analysis. The analogy established is exploited for the interpretation of a decrease in intracavity losses in the system of two coupled cavities with an increase of the extent of mutual coupling at a slight detuning of the cavity lengths. The expediency of the analogy establishment consists of existing difficulties in experimental confirmation of the principles of Rydberg-atom stabilization.
