| Summary: | Impacts of atomic coherence and quantum interference on the optical property of a Doppler-broadened medium are studied both experimentally and theoretically in the multilevel system. The dependence of a two-photon electromagnetically induced transparency width on laser intensity is investigated. Three-photon electromagnetically induced transparency is found for the first time and its physical origin is elucidated. Generalization of double dark resonance is presented, in which counter-intuitive Doppler-free resonance is observed. Electromagnetically induced absorption is also discussed as a counterpart of electromagnetically induced transparency. Potential applications of atomic coherence are demonstrated in terms of optical modulator and quantum switching. The present work develops high-resolution laser spectroscopy via atomic coherence and interference in an inhomogeneous medium. |
