Simultaneous optical and multi-band terahertz imaging using an atomic quantum sensor
Andrew Rae MacKellar, C. Stuart Adams, Kevin J. Weatherill
We demonstrate simultaneous imaging at 0.549 THz and 1.012 THz with an optical overlay using a two-species atomic-vapour-based technique. The atomic vapour, comprising laser-pumped…
Temporally-multiplexed dual-frequency terahertz imaging at kilohertz frame rates
Lucy A. Downes, C. Stuart Adams, Kevin J. Weatherill
We present a temporally-multiplexed dual-colour terahertz (THz) imaging technique using THz-to-optical conversion in atomic vapour. By rapidly alternating the pump laser frequency,…
Continuous time ultra-high frequency (UHF) sensing using ultra-cold Rydberg atoms
Matthew J Jamieson, Kevin J Weatherill, C Stuart Adams +3
We present a technique for detecting ultra-high frequency (UHF) radio fields using a three-photon Rydberg excitation scheme in a continuously laser cooled sample of Rb-87 atoms. By…
Determination of Quantum Defects and Core Polarizability of Atomic Cesium via Terahertz and Radio-Frequency Spectroscopy in Thermal Vapor
Gianluca Allinson, Lucy A. Downes, Kevin J. Weatherill +1
We present new measurements of quantum defects and core polarizabilities in cesium (Cs), based on transition frequency measurements between Rydberg states ($14 \leq n \leq…
