Optical lattice standing wave
WebThe actual technical implementation of conventional interferometers is quite complex and requires manual manufacturing. In combination with the required construction space defined by the optical setup, their applications are limited to selected measuring tasks. In contrast, Standing Wave Interferometers (SWIs) offer an enormous potential for … WebJul 5, 2013 · The basic principle of optical lattices relies on the optical dipole force: when neutral atoms are subjected to an ac electric field, this field dynamically induces a polarization into the atom. The induced dipole moment, in turn, interacts with the electric field and a force is exerted onto the atom.

WebStanding-wave laser fields produce a periodic potential for atoms, which can trap cold atoms in an ordered crystallike structure. 1 In most optical lattices studied so far, the light is tuned close to a resonance, so that spontaneous emission limits the atomic coherence time. Webstanding wave has the form V lat (x) = V 0 sin2(k L x), where k L = 2π/λ L is the wave vector of the laser light used to form the optical standing wave and V 0 represents the lattice …
WebAug 9, 2024 · When the distance L between BECs and mirror and laser frequency f are fixed, we can realize the misplacement of d/4 of the two sets of standing wave optical lattices by adjusting the frequency difference δf. Because δf ≪ f, the lattice constants of the two lattices can be regarded as the same. There are two important parameters of an optical lattice: the potential well depth and the periodicity. The potential experienced by the atoms is related to the intensity of the laser used to generate the optical lattice. The potential depth of the optical lattice can be tuned in real time by changing the power of the laser, which is normally controlled by an acousto-optic modulator (AOM). The AOM i…
Among their many uses, laser beams can trap matter such as atoms and molecules. Two or more intersecting laser beams can combine and “interfere” to form a standing wave, an array of peaks and valleys of light intensity. Depending on the number and arrangement of the laser beams, the standing wave can extend in … See more Soviet physicist Vladilen Letokhov introduced the idea(link is external)of optical lattices more than a half century ago, in the 1960s.
