Active compensation of the AC Stark shift in a two-photon rubidium optical frequency reference using power modulation
Yorick Andeweg, John Kitching, Matthew T. Hummon
We implement a feedback protocol to suppress the AC Stark shift in a two-photon rubidium optical frequency reference, reducing its sensitivity to optical power variations by a fact…
Light shift suppression in a CPT magnetometer using linear polarization and double frequency interrogation
M. A. Maldonado, Yang Li, James A. McKelvy +5
We demonstrate a suppression of the light shift in a Coherent-Population-Trapping (CPT) atomic magnetometer by using linearly polarized light and a differential measurement between…
Sub-Doppler spectroscopy of the strontium intercombination line in a microfabricated vapor cell
Yang Li, John Kitching, Matthew T. Hummon
We report a 100 kHz linewidth for the 1S0 to 3P1 intercombination line of 88Sr atoms at 689nm in a microfabricated 9x14 x4.4 mm3 vapor cell. This puts an upper bound on the residua…
Wafer-scale fabrication of evacuated alkali vapor cells
Yang Li, Donggyu B. Sohn, Matthew Hummon +2
We describe a process for fabricating a wafer-scale array of alkali metal vapor cells with low residual gas pressure. We show that by etching long, thin channels between the cells…
Miniaturized optical frequency standard for next-generation portable optical clocks
Vincent Maurice, Zachary L. Newman, Susannah Dickerson +7
Optical frequency standards, lasers stabilized to atomic or molecular transitions, are widely used in length metrology and laser ranging, provide a backbone for optical communicati…
