gMOT Grating

Kelvin Nanotechnology (KNT), an advanced photonics and quantum component company, announces release of a new grating chip, gMOT. A compact grating Magneto-Optical Trap Chip for the generation of Ultra Cold Atoms of 87Rb. The grating can trap over 10 million 87Rb atoms, with atom clouds denser than 1010/cm3, cooling below 40 µK.

The microfabricated gMOT enables laser cooling with a single laser beam while significantly simplifying optical access requirements and reducing cost.

Applications are in quantum technology research.
