Enhancing fiber atom interferometer by in-fiber laser cooling
We demonstrate an inertia sensitive atom interferometer optically guided inside a 22-cm-long negative curvature hollow-core photonic crystal fiber with an interferometer time of 20 ms. The result prolongs the previous fiber guided atom interferometer time by three orders of magnitude. The improve...

description |
We demonstrate an inertia sensitive atom interferometer optically guided
inside a 22-cm-long negative curvature hollow-core photonic crystal fiber with
an interferometer time of 20 ms. The result prolongs the previous fiber guided
atom interferometer time by three orders of magnitude. The improvement arises
from the realization of in-fiber {\Lambda}-enhanced gray molasses and
delta-kick cooling to cool atoms from 32 {\mu}K to below 1 {\mu}K in 4 ms. The
in-fiber cooling overcomes the inevitable heating during the atom loading
process and allows a shallow guiding optical potential to minimize decoherence.
Our results permit bringing atoms close to source fields for sensing and could
lead to compact inertial quantum sensors with a sub-millimeter resolution. |
