Cooling and trapping of ultra-cold strontium isotopic mixtures
N. Poli, R. E. Drullinger, G. Ferrari +3
We present the simultaneous cooling and trapping of an isotopic mixture in a magneto-optical trap and we describe the transfer of the mixture into a conservative, far-off resonant…
Cooling of Sr to high phase-space density by laser and sympathetic cooling in isotopic mixtures
G. Ferrari, R. E. Drullinger, N. Poli +2
Based on an experimental study of two-body and three-body collisions in ultracold strontium samples, a novel optical-sympathetic cooling method in isotopic mixtures is demonstrated…
Precision frequency measurement of visible intercombination lines of strontium
G. Ferrari, P. Cancio, R. Drullinger +5
We report the direct frequency measurement of the visible 5s S-5s 5pP intercombination line of strontium that is considered a possible candidate for a future op…
Testing the stability of fundamental constants with the 199Hg+ single-ion optical clock
S. Bize, S. A. Diddams, U. Tanaka +10
Over a two-year duration, we have compared the frequency of the 199Hg+ 5d106s 2S 1/2 (F=0)<-> 5d9 6s2 2D 5/2 (F=2) electric-quadrupole transition at 282 nm with the frequency of th…
Absolute Frequency Measurements of the Hg^+ and Ca Optical Clock Transitions with a Femtosecond Laser
Th. Udem, S. A. Diddams, K. R. Vogel +7
The frequency comb created by a femtosecond mode-locked laser and a microstructured fiber is used to phase coherently measure the frequencies of both the Hg^+ and Ca optical standa…
