Noise-Immune Conjugate Large-Area Atom Interferometers
Sven Herrmann, Sheng-wey Chiow, Steven Chu +1
We present a pair of simultaneous conjugate Ramsey-Borde atom interferometers (SCI) using large (20\hbar k)-momentum transfer (LMT) beam splitters, where \hbar k is the photon mome…
Atom Interferometry with up to 24-Photon-Momentum-Transfer Beam Splitters
Holger Mueller, Sheng-wey Chiow, Quan Long +2
We present up to 24-photon Bragg diffraction as a beam splitter in light-pulse atom interferometers to achieve the largest splitting in momentum space so far. Relative to the 2-pho…
Phase-Locked, Low-Noise, Frequency Agile Titanium: Sapphire Lasers for Simultaneous Atom Interferometers
Holger Mueller, Sheng-wey Chiow, Quan Long +1
We demonstrate phase lock of two >1.6W Titanium:sapphire lasers with a phase noise of -138dBc/Hz at 1MHz from the carrier, using an intra-cavity electro-optic phase modulator. The…
