    "abstract": "We report the observation of multiple laser thresholds in the many-atom\ncavity QED microlaser. Traveling-wave coupling and a supersonic atom beam are\nused to create a well-defined atom-cavity interaction. Multiple thresholds are\nobserved as jumps in photon number due to oscillatory gain. Although the number\nof intra-cavity atoms is large, up to N~1000, the dynamics of the microlaser\nagree with a single atom theory. This agreement is supported by quantum\ntrajectory simulations of a many-atom microlaser and a semiclassical microlaser\ntheory. We discuss the relation of the microlaser with the micromaser and\nconventional lasers.",
