We present an experimental study of a vertical-cavity surface-emitting laser with polarized optical feedback. The system displays single-mode low-frequency fluctuations for a large interval of pump current. The dynamics is determined by phenomena extending on a wide range of time scales. In particular, we show, besides rare power drops (events), a periodic structure within the single event, a slow temporal drift in this pattern, and a coherence extending over several events.
