Title (EN) PULSED SCALAR ATOMIC MAGNETOMETER
(FR) MAGNÉTOMÈTRE ATOMIQUE SCALAIRE PULSÉ
Abstract:
(EN) Disclosed is a method and apparatus relating generally to scalar atomic magnetometers. The disclosed methods and apparatus utilize a pressurized sample chamber and a high frequency pulsed pump laser to increase spin polarization and significantly suppress heading errors. These methods and apparatus may also include alternating polarization of the pump light between pulses.
(FR) L'invention concerne un procédé et un appareil se rapportant de façon générale à des magnétomètres atomiques scalaires. Les procédés et l'appareil selon l'invention utilisent une chambre d'échantillonnage sous pression et un laser de pompage pulsé haute fréquence pour augmenter la polarisation de spin et supprimer de façon significative les erreurs de cap. Ces procédés et cet appareil peuvent également comprendre l'alternance de la polarisation de la lumière de pompage entre des impulsions.
