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,…

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…
