Optical deceleration of atomic hydrogen
S. F. Cooper, C. Rasor, R. G. Bullis +2
High-precision hydrogen spectroscopy is an active field which helps to determine the Rydberg constant and proton charge radius, tests bound-state QED, and can search for Beyond Sta…
Frequency-Stabilized Deep-UV Laser at 243.1 nm with 1.4 W output power
Z. Burkley, A. D. Brandt, C. Rasor +2
We demonstrate a 1.4 W continuous wavelength (CW) laser at 243.1 nm. The radiation is generated through frequency quadrupling the output of a ytterbium-doped fiber amplifier system…
Extreme Ultraviolet Radiation With Coherence Time Greater Than 1 s
Craig Benko, Thomas K. Allison, Arman Cingöz +4
Many atomic and molecular systems of fundamental interest possess resonance frequencies in the extreme ultraviolet (XUV) where laser technology is limited and radiation sources hav…
Direct Frequency Comb Spectroscopy in the Extreme Ultraviolet
Arman Cingoz, Dylan C. Yost, Thomas K. Allison +4
Development of the optical frequency comb has revolutionised metrology and precision spectroscopy due to its ability to provide a precise and direct link between microwave and opti…
Extreme Nonlinear Optics in a Femtosecond Enhancement Cavity
T. K. Allison, A. Cingöz, D. C. Yost +1
Intrinsic to the process of high-order harmonic generation is the creation of plasma and the resulting spatiotemporal distortions of the driving laser pulse. Inside a high finesse…
Broadband Phase-Noise Suppression in a Yb-Fiber Frequency Comb
A. Cingoz, D. C. Yost, T. K. Allison +4
We report a simple technique to suppress high frequency phase noise of a Yb-based fiber optical frequency comb using an active intensity noise servo. Out-of-loop measurements of th…
