Magic Velocity Selection in Atom Interferometry
Yuno Iwasaki, Jack Roth, Madeline Bernstein +2
Velocity-selective Raman transitions are widely used in atom interferometers to prepare atomic ensembles with narrowly defined momentum distributions. However, differential light s…
Serrodyne Matterwave Optics
Jack Roth, Madeline Bernstein, Andrew Christensen +4
Bragg diffraction for atom interferometry conventionally requires two laser frequencies whose difference makes the two-photon transition resonant. We show that this frequency diffe…
A fast and accurate method for simulating Bragg atom interferometers
Jack Roth, Andrew Christensen, Madeline Bernstein +2
Atom interferometers are used in a variety of applications, from measuring gravity and gravity gradients in the field to performing tests of fundamental physics in the lab. One met…
Linewidth narrowing and wideband frequency modulation of a DBR laser
Jack Roth, Andrew Christensen, Madeline Bernstein +3
We present a scheme to phase-lock a 240 mW, 852 nm distributed Bragg reflector (DBR) laser to a fixed-frequency narrow-linewidth laser with a rapidly tunable frequency offset near…
Laser cooling Rydberg molecules -- a detailed study of the helium dimer
LucÃa Verdegay, Bingcheng Zeng, Daniel Y. Knapp +2
The helium dimer in its metastable triplet state is a promising candidate to be the first laser-cooled homonuclear molecule. An ultracold gas of He would enable a new generat…
