The scheme also presents a simple way to frequency offset two lasers many gigahertz apart which should find a use in atom cooling experiments, where hyperfine ground-state frequency separations are often required 780 nm narrowband laser sources (corresponding to Rubidium D2 line) are useful for cooling and trapping atoms for, by example, Bose-Einstein condensation or gravimetry applications [1]. High stability laser source for cold atoms applications . Cold atoms research, which historically started as part of the atomic physics field, has grown into a wide, highly interdisciplinary research effort. Building upon developments of laser cooling and trapping [1] and the demonstration of a Bose-Einstein Condensate (BEC) [2], the field now Laser cooling of atoms is a powerful and widely used tool in atomic physics. Traditional laser cooling relies primarily on the mechanical effect of single-photon transitions between ground states and electronically excited states. The goal of this project was to extend these techniques to explore using multiple laser wavelengths and excited-to-excited state transitions to cool and trap atoms Cite this article: ZHUANG Wei,LI Tianchu.

The most commonly used laser cooling schemes in atom optics are Doppler cooling and polarization gradient or Sisyphus cooling. Raman laser cooling and (resolved) sideband cooling are sometimes used together with trapped atoms and more frequently applied for ions in traps. More exotic but physically also interesting laser cooling schemes are VSCPT These MgO:PPLN based laser systems have been used in several applications including, a demonstration of a quantum superposition over 54 centimetres [3], a precision gravimeter [4], a dual-species atom interferometer for BECs [5], and a new type of sensor which simultaneously measures gravity and magnetic field gradients to a high precision [6]. Cooling of a trapped ion to the quantum regime.

A variety of methods have been found for cooling isolated atoms and ions to lower temperatures (Wine-land and Itano, 1987; Wieman and Chu, 1989; Cohen-Tannoudji and Phillips, 1990). These include sub-Doppler laser cooling, evaporative cooling, and laser ‘‘sideband’’ cooling. Sub-Doppler laser cooling uses

The laser series performance was tailored using input from some of the leading researchers in the field of laser cooling. Cool, trap and manipulate atoms, ions, micro-particles using laser light. – Isolate particles from environment – Virtually no Doppler shifts – Extremely long interaction times – BEC, superfluidity.

Laser cooling is a method of slowing down atoms, and thus cooling them, using lasers. Typically we view lasers as heating things up, and they certainly do on macroscopic scales, but for individual atoms or small groups of atoms, they can be used for cooling.
