Watt-class injection-locked diode laser system at 399 nm for atomic physics
Rose Ranson, Yifan Zhou, Michael Hesford +4
We demonstrate an injection-locked 399 nm laser system with up to 1 W output power and a locked power fraction of 0.57. The system consists of a high power, multimode diode laser t…
Ytterbium atom interferometry for dark matter searches
Yifan Zhou, Rowan Ranson, Michalis Panagiotou +1
We analyze the projected sensitivity of a laboratory-scale ytterbium atom interferometer to scalar, vector, and axion dark matter signals. A frequency ratio measurement between two…
A 40 W, 780 nm laser system with compensated dual beam splitters for atom interferometry
Minjeong Kim, Remy Notermans, Chris Overstreet +3
We demonstrate a narrow-linewidth 780 nm laser system with up to 40 W power and a frequency modulation bandwidth of 230 MHz. Efficient overlap on nonlinear optical elements combine…
Physically significant phase shifts in matter-wave interferometry
Chris Overstreet, Peter Asenbaum, Mark A. Kasevich
Many different formalisms exist for computing the phase of a matter-wave interferometer. However, it can be challenging to develop physical intuition about what a particular interf…
Atom-interferometric test of the equivalence principle at the level
Peter Asenbaum, Chris Overstreet, Minjeong Kim +2
Does gravity influence local measurements? We use a dual-species atom interferometer with of free-fall time to measure the relative acceleration between Rb and…
Effective inertial frame in an atom interferometric test of the equivalence principle
Chris Overstreet, Peter Asenbaum, Tim Kovachy +3
In an ideal test of the equivalence principle, the test masses fall in a common inertial frame. A real experiment is affected by gravity gradients, which introduce systematic error…
Phase shift in atom interferometry due to spacetime curvature
Peter Asenbaum, Chris Overstreet, Tim Kovachy +3
We present a single-source dual atom interferometer and utilize it as a gradiometer for precise gravitational measurements. The macroscopic separation between interfering atomic wa…
Matter wave lensing to picokelvin temperatures
Tim Kovachy, Jason M. Hogan, Alex Sugarbaker +4
Using a matter wave lens and a long time-of-flight, we cool an ensemble of Rb-87 atoms in two dimensions to an effective temperature of less than ~pK. A short pulse…
