Abstract: A CO2 frequency-locked laser to an external reference is shown to have oscillatory and eventually chaotic behavior. A linear stability analysis shows that the steady state can be achieved only when the injected CO2 laser field is resonant with the internal one. When detuning is accounted for, the effective laser frequency is either the internal or the external one. The first case is obtained in the limit to zero injected field amplitude A, the second one requires A strong enough to completely slave the system. If A has intermediate values, the output intensity is unstable because of comprtition between modes of operation. Through more and more complicate intensity oscillation patterns, the system is shown numerically to yield oscillations of increasing complexity, up to chaos, this being reached via intermittency.
