    "abstract": "A novel, 3-dimensional, convex, multi-pass optical cavity with\npartially-chaotic ray dynamics is presented. The light is localized near\nstable, long-path length trajectories supported by the cavity, and beam\ndiffraction is suppressed by the phase space barriers between the regions of\nregular and chaotic ray dynamics that are generally present in\npartially-chaotic systems. For a centimeter-size cavity, the design supports\nmeter-scale optical path lengths, suggesting future applications in trace gas\ndetection. An exemplary cavity has been fabricated from a hollow, gold-coated,\nacrylic shell. Our measurements using a HeNe laser and a pulsed red diode laser\nfor characterization of the cavity beam pattern and optical path length,\nrespectively, confirm the theoretically predicted optical dynamics and the\nability of the cavity to support meter-scale path lengths.",
