FPGA-based residual amplitude modulation suppression and control for compact atomic clocks
Tin Nghia Nguyen, Thomas R. Schibli
We designed an FPGA fabric to provide phase modulation techniques to lock lasers to optical frequency references. The method incorporates an active residual-amplitude-modulation (R…
Temperature shift suppression scheme for two-photon two-color rubidium vapor clocks
Tin Nghia Nguyen, Thomas R. Schibli
We propose a new scheme for interrogating a warm rubidium vapor using two different clock lasers. Performance-wise, this approach is distinctly different from the recently proposed…
VUV frequency combs from below-threshold harmonics
Dylan C. Yost, Thomas R. Schibli, Jun Ye +4
Recent demonstrations of high-harmonic generation (HHG) at very high repetition frequencies (~100 MHz) may allow for the revolutionary transfer of frequency combs to the vacuum ult…
Prospects for precision measurements of atomic helium using direct frequency comb spectroscopy
E. E. Eyler, D. E. Chieda, Matthew C. Stowe +3
We analyze several possibilities for precisely measuring electronic transitions in atomic helium by the direct use of phase-stabilized femtosecond frequency combs. Because the comb…
