Precision frequency measurement of visible intercombination lines of strontium.
We report the direct frequency measurement of the visible 5s(2) 1S0-5s5p 3P1 intercombination line of strontium that is considered a possible candidate for a future optical-frequency standard. The frequency of a cavity-stabilized laser is locked to the saturated fluorescence in a thermal Sr atomic beam and is measured with an optical-frequency comb generator referenced to the SI second through ...
متن کاملMeasurement of the cross sections for collisional broadening of the intercombination transitions in calcium and strontium.
We employ an alternative technique for determining the Lorentzian linewidth based upon the simultaneous measurement of the vapor transmission and group-velocity delay outside the Doppler core of an optically dense transition. We apply this technique to measure the cross sections for broadening of the intercombination lines of calcium, 4s 'S0~4s4p Pi, and strontium, Ss 'S0~5s5p Pi, by collisions...
متن کاملEvaluation of Accuracy, Precision and Agreement of Five Hba1c Measurement Methods with HPLC Reference Method
ABSTRACT Background and Objective: The current challenge of diabetes mellitus is to prevent its complications. These complications are directly associated with hyperglycemia in diabetics. The HbA1c measurement is essential for long-term glycemic control. Synchronization of HbA1c measurement is important in order to avoid discrepancies between resu...

15 صفحه اولPrecision measurement and frequency metrology with ultracold atoms
Precision measurement and frequency metrology have pushed many scientific and technological frontiers in the field of atomic, molecular and optical physics. In this article, we provide a brief review on the recent development of optical atomic clocks, with an emphasis placed on the important inter-dependence between measurement precision and systematic effects. After presenting a general discus...
