Sensitive optical atomic magnetometer based on nonlinear magneto-optical rotation
A self-oscillating magnetometer based on nonlinear magneto-optical rotation using amplitude-modulated pump light and unmodulated probe light (AM-NMOR) in Rb has been constructed and tested towards a goal of airborne detection of 87 magnetic anomalies. In AM-NMOR, stroboscopic optical pumping via amplitude modulation of the pump beam creates alignment of the ground electronic state of the rubidi...
متن کاملNonlinear magneto-optical rotation of elliptically polarized light
We predict theoretically and demonstrate experimentally an ellipticity-dependent nonlinear magneto-optic rotation of elliptically polarized light propagating in a medium with atomic coherence. We show that this effect results from hexadecapole and higher-order moments of the atomic coherence, and is associated with an enhancement of Kerr and higher-order nonlinearities accompanied by suppressio...
متن کاملNonlinear magneto-optical rotation in optically thick media
Resonant nonlinear magneto-optical rotation (NMOR) [1, 2] has been the subject of extensive theoretical and experimental studies because it provides a very sensitive way to measure magnetic fields (see, e.g., Ref. [3]). While NMOR experiments are usually carried out with vapor samples of moderate optical thickness (no more than ∼ 2 absorption lengths), the intense research of recent years on el...
متن کاملNonlinear magneto-optical rotation via alignment-to-orientation conversion
Nonlinear magneto-optical rotation is investigated at high light powers where the rotation is significantly modified by ac Stark shifts. These shifts are shown to change the overall sign of rotation for closed F-->F+1 transitions compared to the low light power limit. The effect is demonstrated by measurements in rubidium and density matrix calculations. The results are important for applicatio...
متن کاملSelf-driven nonlinear dynamics in magneto-optical traps
We present a theoretical model describing recently observed collective effects in large magnetooptically trapped atomic ensembles. Based on a kinetic description we develop an efficient test particle method, which in addition to the single atom light pressure accounts for other relevant effects such as laser attenuation and forces due to multiply scattered light with position dependent absorpti...
