The spectroscopy of hot atomic vapours is a hot topic. Many of the work-horse techniques of
contemporary atomic physics were first demonstrated in hot vapours. Alkali-metal atomic …

This tutorial aims to provide details on the underlying principles and methodologies of atom-
based terahertz imaging techniques. Terahertz imaging is a growing field of research which …

Single-cell magneto-optical Faraday filters find great utility and are realized with either
“wing” or “line center” spectral profiles. We show that cascading a second cell with …

Cascading light through two thermal vapour cells has been shown to improve the
performance of atomic filters that aim to maximise peak transmission over a minimised …

窄线宽外腔半导体激光器具有结构简单, 可调谐, 噪声低等优势, 广泛应用于量子精密测量,
光通信, 激光雷达等领域. 根据外腔选频器件的不同, 本文主要介绍光栅型激光器 …

Abstract The Kramers-Kronig relations are a pivotal foundation of linear optics and atomic
physics, embedding a physical connection between the real and imaginary components of …

Atomic bandpass filters are used in a variety of applications due to their narrow bandwidths
and high transmission at specific frequencies. Predominantly, these filters are in the Faraday …

A dual-wavelength bandpass Faraday anomalous dispersion optical filter (DW-FADOF)
operating at both the D1 and D2 lines of rubidium is experimentally demonstrated. The …

The wavelength dependence of the Faraday effect may be measured either sequentially at
particular wavelengths using narrow band sources, or simultaneously at many wavelengths …

We demonstrate a metastable helium Faraday optical filter operating on the 2^ 3S_1− 2^
3P_1 and 2^ 3S_1− 2^ 3P_2 transition at 1083 nm by using a 3 cm long helium cell. The …
