Dynamic synchronisation regions of a ring laser with the use of a periodic support

The method is proposed for calculating dynamic synchronisation regions of a ring laser with a periodic frequency support of a special type. The proposed algorithm in essence taking into account the special type of the support allows the search for minimal widths of regions when the support parameters change. The widths of the regions are calculated as an example for the case of the harmonic carrier modulation as a harmonic envelope (three-frequency support) and an envelope of the "soft" meander type (multifrequency support).
