Cavity-induced phase stability to decelerate a fast molecular beam via feedback-controlled time-varying optical pumps

摘要: We have identified a novel phase stability mechanism from the intracavity field-induced self-organization of fast-moving molecular beam into travelling packets in bad cavity regime, which is then used to decelerate by feedback-controlled time-varying laser pumps cavity. first applied linear analysis derive an expression for this adiabatic limit and show that leads formation packets, turn function as dynamic Bragg grating, thus modulating periodically field superradiant scattering pump photons. The modulation encodes position information output instantaneously. are automatically switched slow down via feedback found most molecules decelerated zero central velocity after tens stages. Our cavity-based deceleration proposal works well very different conventional cooling strategies where good preferred. Practical issues realizing also discussed.
