physics.atom-ph2018

Single-beam Zeeman slower and magneto-optical trap using a nanofabricated grating

D. S. Barker, E. B. Norrgard, N. N. Klimov +3

We demonstrate a compact (0.25 L) system for laser cooling and trapping atoms from a heated dispenser source. Our system uses a nanofabricated diffraction grating to generate a mag…

Challenges to miniaturizing cold atom technology for deployable vacuum metrology

Stephen Eckel, Daniel S. Barker, James A. Fedchak +3

Cold atoms are excellent metrological tools; they currently realize SI time and, soon, SI pressure in the ultra-high (UHV) and extreme high vacuum (XHV) regimes. The development of…

Light-induced atomic desorption of lithium

D. S. Barker, E. B. Norrgard, J. Scherschligt +2

We demonstrate loading of a Li magneto-optical trap using light-induced atomic desorption. The magneto-optical trap confines up to approximately 4×104 7Li ato…
