Record nonlinear conversion efficiency in the production of high spectral purity vacuum ultraviolet laser at 148 nm
Sergey Vasilyev, Tian Ooi, Igor Moskalev +14
Coherent vacuum-ultraviolet (VUV) lasers are indispensable for precision measurement, quantum optics, and materials science. Recent high-resolution spectroscopy of the Th-229 nucle…
Probing Ultralight Dark Matter at the Mega-Planck Scale with the Thorium Nuclear Clock
Jason Arakawa, Jack F. Doyle, Elina Fuchs +10
Ultralight dark matter is expected to induce oscillations of nuclear parameters. These oscillations are characterized by extremely weak couplings or high suppression scales, with t…
Frequency reproducibility of solid-state Th-229 nuclear clocks
Tian Ooi, Jack F. Doyle, Chuankun Zhang +5
Solid-state Th nuclear clocks are set to provide new opportunities for precision metrology and fundamental physics. Taking advantage of a nuclear transition's inherent low…

Frequency ratio of the Th nuclear isomeric transition and the Sr atomic clock
Chuankun Zhang, Tian Ooi, Jacob S. Higgins +9
Optical atomic clocks use electronic energy levels to precisely keep track of time. A clock based on nuclear energy levels promises a next-generation platform for precision…
Tunable VUV Frequency Comb for Th Nuclear Spectroscopy
Chuankun Zhang, Peng Li, Jie Jiang +4
Laser spectroscopy of the Th nuclear clock transition is necessary for the future construction of a nuclear-based optical clock. Precision laser sources with broa…
Concepts for direct frequency-comb spectroscopy of Th and an internal-conversion-based solid-state nuclear clock
Lars von der Wense, Chuankun Zhang
A new concept for narrow-band direct nuclear laser spectroscopy of Th is proposed, using a single comb mode of a vacuum ultraviolet frequency comb generated from th…
Mid-infrared frequency comb generation with silicon nitride nano-photonic waveguides
Clemens Herkommer, Adrien Billat, Hairun Guo +5
Mid-infrared optical frequency combs are of significant interest for molecular spectroscopy due to the large absorption of molecular vibrational modes on one hand, and the ability…
