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

Cold-atom systems are also useful for a long list of other applications, such as highly accurate atomic clocks for ultra-precise GPS systems or systems that can locate hidden objects based on their gravitational pull. 976 Laser Cooling and Trapping of Neutral Atoms 2.3.4 Radiative and Dipole Forces 982 2.3.5 Force on Moving Atoms 982 3 Laser Cooling 982 3.1 Slowing Atomic Beams 982 3.2 Optical Molasses 984 3.2.1 Doppler Cooling 984 3.2.2 Doppler Cooling Limit 985 3.2.3 Atomic Beam Collimation – … Apart from Doppler cooling, some other laser cooling techniques include Sisyphus cooling, Resolved sideband cooling, Raman sideband cooling, cavity mediated cooling, etc., to name a few. In 1997, the Nobel Prize in Physics was awarded to Steven Chu, Claude Cohen-Tannoudji, and William D. Phillips for the development of methods to cool and trap atoms with laser light.

Uses. Laser cooling is primarily used to create ultracold atoms for experiments in quantum physics. By controlling and manipulating the internal, quantum states of matter, one has an extraordinary amount of control over such systems, giving rise to a number of real-world applications.

Conventional laser cooling of atoms relies on photons exciting the electrons inside the atom. When the electron falls back into the ground state, the atom spontaneously emits a photon. Since this photon is emitted in a random direction, the overall effect of the absorption and emission process is to reduce the momentum of the atom – that is, to “cool” it – in the direction of the laser for atom cooling Application Note by QUANTELQUANTEL Distribution: external Doppler cooling requires lasers that emit a very precise wavelength that is precisely shifted from the target cycling transition (typically at 2.5Γ red shifted for optimal atom cooling where Γ is the natural Doppler cooling is a mechanism that can be used to trap and slow the motion of atoms to cool a substance. The term is sometimes used synonymously with laser cooling, though laser cooling includes other techniques.

Typical applications include time/frequency standards (atomic clocks), GPS systems and navigation, research on fundamental constants, quantum information (computing and encryption), and atom interferometry (gravitational detection of natural Atom Cooling application note now available 17 December 2015 Back Quantel Laser just published an Application Note on Atom Cooling, explaining the atom cooling process, which laser performances are requested to do so and how the EYLSA laser by Quantel can be the right option. Doppler cooling is a mechanism that can be used to trap and slow the motion of atoms to cool a substance.

Laser cooling and trapping of neutral atoms* William D. Phillips National Institute of Standards and Technology, Physics Laboratory, Atomic Physics Division, Gaithersburg, Maryland 20899 [S0034-6861(98)00603-5] INTRODUCTION In 1978, while I was a postdoctoral fellow at MIT, I Optical fiber amplifiers for atom cooling or spectroscopy Keopsys has provided many customers with tunable fiber lasers for spectroscopic applications. We offer tunable lasers and broad bandwidth optical fiber amplifiers in the wavelength regions of 1µm, 1,5µm, and 2µm. Frequency-stabilized lasers are widely used for a variety of applications such as laser cooling and trapping of atoms, high-resolution spectroscopy, precision mea-surements and optical communication [1,2]. A typical experimental set-up for laser cooling and trapping of atoms employs several frequency-stabilized lasers tuned to diﬁerent frequencies.
