Abstract
In this paper we present an experimental scheme for controlling the ch aotic regime, reached through quasiperiodicity, of a CO2 laser with de layed electro-optic feedback. This method, bused on a selective filter rejecting one of the two characteristic frequencies of the quasiperio dic motion, allows stabilization of the limit cycle present at the beg inning of the bifurcation sequence. By coupling the CO2 laser model wi th the differential equations of the filter, we obtain numerical resul ts in good agreement with the experimental observation.
