Magneto-optical trap — experimental setup of the MOT A magneto optical trap (abbreviated MOT) is a device that uses both laser cooling with magneto optical trapping in order to produce samples of cold, trapped, neutral atoms at temperatures as low as several… … Wikipedia
Optical tweezers — (originally called single beam gradient force trap ) are scientific instruments that use a highly focused laser beam to provide an attractive or repulsive force (typically on the order of piconewtons), depending on the refractive index mismatch… … Wikipedia
Optical molasses — Schematic Optical molasses is a laser cooling technique that can cool down neutral atoms to temperatures colder than a magneto optical trap (MOT). An optical molasses consists of 3 pairs of counter propagating circularly polarized laser beams… … Wikipedia
Optical levitation — A force diagram showing how vertical and lateral stabilization occurs in a vertically oriented optical trap. Optical levitation is a method developed by Arthur Ashkin whereby a material is levitated against the downward force of gravity by an… … Wikipedia
optical tweezers — (= laser tweezers; optical trap) By focusing a beam of light on a particle it is possible to trap the particle as a result of the forces due to radiation pressure (the forces involved are of the order of pico newtons). Laser beams exert… … Dictionary of molecular biology
Optical lattice — Simulation of an optical lattice potential. An optical lattice is formed by the interference of counter propagating laser beams, creating a spatially periodic polarization pattern. The resulting periodic potential may trap neutral atoms via the… … Wikipedia
Magnetic trap (atoms) — A magnetic trap uses a magnetic gradient to trap neutral particles with a magnetic moment. Although such traps have been employed for many purposes in physics research, they are best known as the last stage in cooling atoms to achieve Bose… … Wikipedia
Magnetic trap — refers to one of three types of traps used for atoms or charged particles: Magnetic trap (atoms), used to trap neutral atoms in a magnetic field gradient Penning trap, used to trap charged particles or ions in a combination of electrostatic… … Wikipedia
Dipole trap — A dipole trap is a system in which a laser (or two lasers) are used to polarize an individual atom for study. The set up is similar to a Magneto optical trap except that there is no magnetic field and a reduced number of lasers. References… … Wikipedia
Quadrupole ion trap — Scheme of a Quadrupole ion trap of classical setup with a particle of positive charge (dark red), surrounded by a cloud of similarly charged particles (light red). The electric field E (blue) is generated by a quadrupole of endcaps (a, positive)… … Wikipedia
