Optical cavity trap
WebJan 25, 2013 · We present the realization of a combined trapped-ion and optical cavity system, in which a single Yb+ ion is confined by a micron-scale ion trap inside a 230 μm -long optical fiber cavity. We characterize the spatial ion-cavity coupling and measure the ion-cavity coupling strength using a cavity-stimulated Λ transition. WebAn optical trap is a measurement device that allows minute forces to be exerted on cells and small tissues using a laser. In a standard setup (Figure 1), a collimated laser beam is …

WebSeveral methods have been demonstrated to trap a large number of atoms within a tight cavity mode. One method is to first load atoms into an auxiliary trap adjacent to the cavity mode, such as a magnetic trap or another optical lattice, and to move the atoms to overlap spatially with the cavity mode [30,31].
Finally, we demonstrate that the thermo-optic feedback allows for fully stable self-locking of the cavity near resonance.
