Abstract: Self-pulsing and deterministic chaos is observed in a single-mode, homogeneous-line, C02 laser with an overall negative feedback, when the damping constant of the feedback loop is of the same order as the population decay rate. This represents a fundamental limitation of the general use of feedback schemes in high-stability laser applications. A theoretical model is shown to yield results in good agreement with the experimental ones, thus confirming the simple structure of the associated phase space.
