Quantum electrodynamics (QED), a theory about radiation fields, is the most accurate and widely applicable physical theory currently known. Cavity QED examines what happens to those radiation fields when they are confined to a cavity (a cavity can be thought of as an atomic pot-hole). Confined radiation fields interact quite differently with atoms than unconfined fields. This difference gives cavity QED the potential for some important applications that ordinary QED does not have, such as applications to laser technology, and to the high precision measurement of time and frequency.
