Rapid readout of terahertz orbital angular momentum beams using atom-based imaging
Lucy A. Downes, Daniel J. Whiting, Charles S. Adams +1
We demonstrate the rapid readout of terahertz (THz) orbital angular momentum (OAM) beams using an atomic-vapour based imaging technique. OAM modes with both azimuthal and radial in…
Ultra-high-speed Terahertz Imaging Using Atomic Vapour
Lucy A. Downes, Andrew R. MacKellar, Daniel J. Whiting +3
Terahertz (THz) technologies, generally defined as operating in the 0.1-10THz range, bridge the gap between electronic and photonic devices. Because THz radiation passes readily th…
Simultaneous two-photon resonant optical laser locking (STROLLing) in the hyperfine Paschen--Back regime
Renju S. Mathew, Francisco Ponciano-Ojeda, James Keaveney +2
We demonstrate a technique to lock simultaneously two laser frequencies to each step of a two-photon transition in the presence of a magnetic field sufficiently large to gain acces…
Low-drift Zeeman shifted atomic frequency reference
D. J. Reed, N. Šibalić, D. J. Whiting +3
We present a simple method for producing a low-drift atomic frequency reference based upon the Zeeman effect. Our Zeeman Shifted Atomic Reference `ZSAR' is demonstrated to have ten…
Four-wave mixing in a non-degenerate four-level diamond configuration in the hyperfine Paschen-Back regime
Daniel J. Whiting, Renju S. Mathew, James Keaveney +2
We present an experimental study of seeded four-wave mixing (4WM) using a diamond excitation scheme (with states from the 5S, 5P, 5P and 5D terms) i…
Single-photon interference due to motion in an atomic collective excitation
Daniel J. Whiting, Nikola Sibalic, James Keaveney +2
We experimentally demonstrate the generation of heralded bi-chromatic single photons from an atomic collective spin excitation (CSE). The photon arrival times display collective qu…
