Cold Atom Interferometry
Thanks to the wave character of atoms, atom interferometry profits from the shorter de Broglie wavelength than light and delivers higher precision in comparison to optical interferometry. In such a interferometer, laser sources with very high precision and low noise are used as mirrors, gratings and beam splitters. Atoms can be cooled and manipulated according to need, a conventional configuration mirrors the classic Mach-Zehnder interferometer, there the phase difference of atoms coherently split into different arms is compared.
The atomic interferometer has been used in fundamental research regarding gravitational constant, fine-structure constant, and the detection of gravitational waves. It can also be used in aviation. systems as accelerometers, inertial sensors, and gravity gradiometers.
As a long time player in the cold atom field, we provide some of the most stable solutions for cold atom applications. With the DFB and miniECL as seeder and TPA as power amplifier, very precise interactions with various atoms can be achieved, we cover the most common atoms such as Rb and Cs.
