A compact stabilized three-laser optical pump system for an imaging system based on THz-to-visible conversion via atomic vapour
Quantum Sensing and Nano Electronics and Photonics XVIII(2022)
摘要
THz imaging often struggles to achieve necessary framerates for applications, but recent demonstrations show that an imaging system based upon THz-to-optical conversion in atomic vapour can provide ultrahigh speeds while retaining sensitivity with optical cameras. This atomic vapour imaging requires a multi-frequency near-IR optical pumping system, and we demonstrate a compact system to provide the stable frequencies required for conversion of 0.55 THz light to visible (green) in caesium atoms. Through the integration of distributed feedback (DFB) laser diodes and a compact extended cavity diode laser, and spectroscopy and offset locks based on open-source FPGA and Arduino code, it approaches suitability for wider industrial application.
