Laser cooling

DESCRIPTION

Laser cooling is a unique technique that uses a laser beam to cool and trap atoms/ions to near absolute zero. It enables us to study the quantum nature of atoms/ions at cryogenic temperatures. The main applications are time/frequency standards (atomic clocks) and quantum computer experiments.
Laser cooling requires very precise control of the laser wavelengths to match the energy of the electronic transitions of a particular atom/ion. NTT Electronics' wavelength conversion module uses near-infrared lasers, which are available in a wide range of wavelengths including semiconductor LDs, to generate visible light and make it possible to build compact reliable systems.
