Optical cavity trap
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]. WebThe cavity is assumed to be arranged around the centre of an ion trap, and as such is limited in its minimum length and maximum mirror diameter, due to the need to minimise exposure of the ion...

WebNov 15, 2015 · First steps along these lines were taken by releasing cold atoms from a magneto-optical trap (MOT) such that they fall through a high-finesse optical cavity [5, 6]. Interaction times were further increased with an atomic fountain with the cavity at the turning point of the atoms [7, 8]. The only way to further improve was then to employ an … WebIn this section, we propose a scheme to trap 2D ion crystals with optical cavity trap.

WebApr 12, 2024 · In nature, jellyfish are one of the most energy-efficient underwater animals due to their locomotion modes, i.e., jet-based or paddling-based swimming ().Moreover, how jellyfish swim combines effective fluidic propulsion and object manipulation, which is beneficial for predation (8, 12, 13).Furthermore, their deformable soft body structure … An optical cavity, resonating cavity or optical resonator is an arrangement of mirrors or other optical elements that forms a cavity resonator for light waves. Optical cavities are a major component of lasers, surrounding the gain medium and providing feedback of the laser light. They are also used in optical parametric oscillators and some interferometers. Light confined in the cavity reflects multiple times, producing modes with certain resonance frequencies. Modes can b…
