Soft X-ray high-harmonic generation in an anti-resonant hollow core fiber driven by a 3 m ultrafast laser
Drew Morrill, Will Hettel, Daniel Carlson +15
High-harmonic upconversion driven by a mid-infrared femtosecond laser can generate coherent soft X-ray beams in a tabletop-scale setup. Here, we report on a compact ytterbium-pumpe…

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…
