Narrow-Line Electric Quadrupole Cooling And Background-Free Imaging Of A Single Cs Atom With Spatially Structured Light
Karl N. Blodgett, Saumitra S. Phatak, Meng Raymond Chen +3
We demonstrate background-free imaging and sideband cooling of a single 133Cs atom via the narrow-line 6S1/2 to 5D5/2 electric quadrupole transition in a 1064 nm optical tweezer. T…

A Generalized Theory for Optical Cooling of a Trapped Atom with Spin
Saumitra S. Phatak, Karl N. Blodgett, David Peana +2
Cooling atoms to the ground-state of optical tweezers is becoming increasingly important for high-fidelity imaging, cooling, and molecular assembly. While extensive theoretical wor…

Imaging a Li Atom In An Optical Tweezer 2000 Times with -Enhanced Gray Molasses
Karl N. Blodgett, David Peana, Saumitra Phatak +3
We have imaged lithium-6 thousands of times in an optical tweezer using -enhanced gray molasses cooling light. Despite being the lightest alkali, with a recoil temperature of 3.…
