    "abstract": "We demonstrate phase and frequency stabilization of a diode laser at the\nthermal noise limit of a passive optical cavity. The system is compact and\nexploits a cavity design that reduces vibration sensitivity. The sub-Hz laser\nis characterized by comparison to a second independent system with similar\nfractional frequency stability (1 x 10-15 at 1 s). The laser is further\ncharacterized by resolving a 2 Hz wide, ultranarrow optical clock transition in\nultracold strontium.",
