A Compact, High Performance Atomic Magnetometer for Biomedical Applications
Vishal K. Shah, Ronald T. Wakai
We present a highly sensitive room-temperature atomic magnetometer (AM), designed for use in biomedical applications. The magnetometer sensor head is only 2x2x5 cm^3 and it is cons…
Stroboscopic back-action evasion in a dense alkali-metal vapor
G. Vasilakis, V. Shah, M. V. Romalis
We explore experimentally quantum non-demolition (QND) measurements of atomic spin in a hot potassium vapor in the presence of spin-exchange relaxation. We demonstrate a new techni…
High Bandwidth Atomic Magnetometery with Continuous Quantum Non-demolition Measurements
V. Shah, G. Vasilakis, M. V. Romalis
We describe an experimental study of spin-projection noise in a high sensitivity alkali-metal magnetometer. We demonstrate a four-fold improvement in the measurement bandwidth of t…
Spin-Exchange-Relaxation-Free Magnetometry Using Elliptically-Polarized Light
V. Shah, M. V. Romalis
Spin-exchange relaxation free alkali-metal magnetometers typically operate in the regime of high optical density, presenting challenges for simple and efficient optical pumping and…
