Ultrastable optical frequency dissemination over a branching passive optical network using CDMA
Rodrigo González Escudero, Sougandh Kannoth Mavila, Jeroen C. J. Koelemeij
We demonstrate a technique for ultrastable optical frequency dissemination in a branching passive optical network using code-division multiple access (CDMA). In our protocol, each…
Coherent Three-Photon Excitation of the Strontium Clock Transition
Junyu He, Benjamin Pasquiou, Rodrigo Gonzalez Escudero +3
We demonstrate coherent three-photon excitation of the strontium clock transition with a contrast of 51(12)% using a Bose-Einstein condensate. We follow it up with a demonstration…
Optical pumping of strontium atoms for laser cooling and imaging
Jens Samland, Shayne Bennetts, Chun-Chia Chen +3
We present a faster repumping scheme for strontium magneto-optical traps operating on the broad laser cooling tran…
A steady-state magneto-optical trap of fermionic strontium on a narrow-line transition
Rodrigo González Escudero, Chun-Chia Chen, Shayne Bennetts +2
A steady-state magneto-optical trap (MOT) of fermionic strontium atoms operating on the 7.5 kHz-wide transition is demonstrated. This MOT feat…
Continuous guided strontium beam with high phase-space density
Chun-Chia Chen, Shayne Bennetts, Rodrigo González Escudero +2
A continuous guided atomic beam of with a phase-space density exceeding in the moving frame and a flux of is…
Sisyphus Optical Lattice Decelerator
Chun-Chia Chen, Shayne Bennetts, Rodrigo González Escudero +2
We experimentally demonstrate a variation on a Sisyphus cooling technique that was proposed for cooling antihydrogen. In our implementation, atoms are selectively excited to an ele…
