Optical Rotation Detection for Atomic Spin Precession Using a Superluminescent Diode
Superluminescent diode atomic magnetometer magnetoencephalography atomic spin precession detection Larmor precession
Abstract
A superluminescent diode (SLD) as an alternative of laser is used to detect optical rotation for atomic spin precession. A more uniform Gauss configuration without additional beam shaping and a relatively high power of the SLD have a potential for atomic magnetometers, which is demonstrated in theory and experiments. In addition, the robustness and compactness enable a more practical way for optical rotation detections, especially for applications in magnetoencephalography systems.
