چکیده

Dark line resonances, narrowed with a buffer gas to less than 100 Hz width, are observed in a Cs vapor cell using a directly modulated vertical-cavity surface-emitting laser (VCSEL). An external oscillator locked to one of these resonances exhibits a short-term stability of ( ) = 9 3 10 12 , which drops to 1 6 10 12 at 100 s. A physics package for a frequency-reference based on this design could be compact, low-power, and simple to implement.

Characterization of coherent population-trapping resonances as atomic frequency references

A low-cost, potentially compact and robust microwave frequency reference can be constructed by use of vertical-cavity surface-emitting lasers and coherent population-trapping resonances in Cs vapor cells. Fractional frequency instabilities of 2 3 10211/At/s have been achieved with a minimum of 7 3 10213 at t 5 1000 s. The performance of this device as a function of external parameters such as l...

Performance of a prototype atomic clock based on lin‖ lin coherent population trapping resonances in Rb atomic vapor

We report on the performance of the first table-top prototype atomic clock based on coherent population trapping (CPT) resonances with parallel linearly polarized optical fields (lin lin configuration). Our apparatus uses a vertical-cavity surface-emitting laser (VCSEL) tuned to the D1 line of Rb with the current modulation at the Rb hyperfine frequency. We demonstrate cancellation of the first...

Saturated absorption spectroscopy: elimination of crossover resonances by use of a nanocell

It is demonstrated that velocity selective optical pumping/saturation resonances of reduced absorption in a Rb vapor nanocell with thickness L= λ, 2λ, and 3λ (resonant wavelength λ = 780 nm) allow the complete elimination of crossover (CO) resonances. We observe well pronounced resonances corresponding to the Fg = 3 → Fe = 2, 3, 4 hyperfine transitions of the Rb D2 line with linewidths close to...

Dark resonances in potassium vapor for absolute measurement of magnetic fields

In this communication, we present a new approach for development of optical magnetometer based on the D2 line of potassium (K), where the hyperfine transitions are strongly overlapped. Magnetically unshielded, 8-mm-long cell (containing K + 30Torr Ne) is introduced, in order to reduce the gradients influence of laboratory magnetic field Blab to spectral width of Dark Resonances (DRs), which are...

Metrological characterization of custom-designed 894.6 nm VCSELs for miniature atomic clocks.

We report on the characterization and validation of custom-designed 894.6 nm vertical-cavity surface-emitting lasers (VCSELs), for use in miniature Cs atomic clocks based on coherent population trapping (CPT). The laser relative intensity noise (RIN) is measured to be 1 × 10(-11) Hz(-1) at 10 Hz Fourier frequency, for a laser power of 700 μW. The VCSEL frequency noise is 10(13) · f(-1) Hz(2)/Hz...
