The spatial dynamics of an optical ring phase-conjugated resonator with Standard chaos is presented. It is shown that thisbehavior takes place when a specific chaos-generating element is introduced on the resonator. Assuming ray optics inside the cavitywith parameterspandθfor the effective distance to the optical axis and the angle to the same axis (beam’s divergence) respectively.The matrix of a standard map generating device is found in terms of the specific map parameters, the state variables and theresonatorparameters. One interesting feature of these kind of systems is that allow to model different bigger and uncontrollablesystems, e.g.ocean dynamics, weather, social and economical systems, among others; This feature is possible thanks to the parameters controlfacility
