Abstract
We describe a novel atom interferometry technique for manipulating Bose-Einstein Condensate. The technique requires a Bose-Einstein condensate, which will be manipulated using pulsed, off-resonant laser beams. The new technique permits a larger interferometer arm separation and longer separation times compared to previous experiments, thus providing greater sensitivity to gravity. To achieve such feat we need the pulsed beams’ phase stabilized via an electro-optical active feedback system. Such apparatus is built and demonstrated to manipulate ultra cold atoms with precision. We present interferometry measurements to accurately ascertain the recoil velocity of the 87Rb atoms to less than 1% of the theoretical value. This work lays the foundation for the next generation gravity measurement improving the sensitivity over the current existing instruments.
