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…
Extended cavity diode lasers with tracked resonances
Sheng-wey Chiow, Quan Long, Christoph Vo +2
We present a painless, almost-free upgrade to present extended cavity diode lasers (ECDLs), which improves the long term mode-hop free performance by stabilizing the resonance of t…
A new photon recoil experiment: towards a determination of the fine structure constant
Holger Mueller, Sheng-wey Chiow, Quan Long +2
We report on progress towards a measurement of the fine structure constant to an accuracy of or better by measuring the ratio of the Planck constant to the mass…
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…
Active sub-Rayleigh alignment of parallel or antiparallel laser beams
Holger Mueller, Sheng-wey Chiow, Quan Long +2
We measure and stabilize the relative angle of (anti-)parallel laser beams to 5 nanoradian per root Hertz resolution by comparing the phases of radio frequency beat notes on a quad…
