Mot trap
Did you know?
A magneto-optical trap (MOT) is an apparatus which uses laser cooling and a spatially-varying magnetic field to create a trap which can produce samples of cold, trapped, neutral atoms. Temperatures achieved in a MOT can be as low as several microkelvin, depending on the atomic species, which is two or three … Se mer Two coils in an anti-Helmholtz configuration are used to generate a weak quadrupolar magnetic field; here, we will consider the coils as being separated along the $${\displaystyle z}$$-axis. In the proximity of the field … Se mer Magnetic trapping is created by adding a spatially varying magnetic quadrupole field to the red detuned optical field needed for laser cooling. This … Se mer Laser All magneto-optical traps require at least one trapping laser plus any necessary repumper lasers (see above). These lasers need stability, rather than high power, requiring no more than the saturation intensity, but a Se mer As a result of low densities and speeds of atoms achieved by optical cooling, the mean free path in a ball of MOT cooled atoms is very long, and atoms may be treated as Se mer Photons have a momentum given by $${\displaystyle \hbar k}$$ (where $${\displaystyle \hbar }$$ is the reduced Planck constant and $${\displaystyle k}$$ the photon wavenumber), which is conserved in all atom-photon interactions. Thus, when an atom … Se mer As a thermal atom at room temperature has many thousands of times the momentum of a single photon, the cooling of an atom must … Se mer The minimum temperature and maximum density of a cloud in a magneto-optical trap is limited by the spontaneously emitted photon in … Se mer Eine magneto-optische Falle (englisch magneto-optical trap, MOT) ist ein Hilfsmittel der Atomphysik, welches zur Kühlung und Speicherung von neutralen Atomen benutzt wird. Kühlung bedeutet hier Abbremsen der Atome, da sich die Temperatur eines einzelnen Atoms durch seine kinetische Energie, also seine Geschwindigkeit ausdrückt. Konkret bedeutet das: Befindet sich eine große A…

THEORY The dynamics of MOT loading and loss are governed, to a good approximation, by the rate equation dN dt = R −γN(t)−βnN¯ (t). (1) Here N is the number of atoms in the trap and R is the rate at which atoms are loaded via laser cooling. Normally, R will
