Atom Cooling and Trapping

The ability to cool, manipulate, and trap atoms using laser light has allowed a new, rapidly expanding field to emerge. Recent publications noting the potential of reaching atomic kinetic-energy temperatures lower than absolute zero, otherwise known as negative temperatures, is one of the most impressive achievements to come out of this field.

Current research focuses on improving existing cooling techniques, and the development of cold atoms as a source for applications ranging from atomic clocks, trapping Rydberg ions, studies of quantum degeneracy, spectroscopy, atomic interferometers, optics, lithography, and gravitational measurements. These fundamental studies are used to develop applications to new kinds of physics measurements and processes such as high resolution spectroscopy, atomic collisions, quantum information processing, quantum simulation, and bio-molecular interactions.

MPB Communications is pleased to have provided high power Single-Frequency NIR Raman Fiber Amplifiers and Visible Raman Fiber Amplifiers to leading research laboratories worldwide which target wavelengths previously unavailable. The flexibility of our technology allows us to develop novel emission wavelengths for use in atomic physics research applications where the need for both the preservation of single longitudinal mode and higher output power is a must. The desk-top sized laser can be set up in 1-2 hours and requires a minimum of maintenance allowing researchers to spend less time taking care of the laser system so they may focus their attention on the research at hand.

Now that’s cool!
