Abstract
In this paper we present a control technique for stabilizing chaotic m otion to periodic orbits in a CO2 laser with electro-optic feedback. T he control method is based on negative feedback of subharmonic compone nts of the laser intensity signal. A detailed analysis, performed usin g the four-level model for the CO2 laser, allows us both to reproduce the experimental features and to compare our method with the time-dela yed autosynchronization method introduced by Pyragas [Phys. Lett. A 17 0, 421 (1992)].
