Physics Colloquium

Optical cavities for bioimaging, atom interferometers, and trapping molecules

Atomic, molecular and optical physics continues to enrich other branches of science. We report creating the world's most intense continuous-wave laser in an optical cavity (~450 GW/cm^2), and applying it to generate phase contrast in transmission electron microscopy, showing that it improves the reconstruction of biological macromolecules. Besides, we discuss how optical cavities find use in atom interferometry with minute-scale coherence and, potentially, as a universal trap for small molecules.
