Multipass cell SERF atomic magnetometer based on parallel plate configuration
Optics LettersWe introduce a novel, to the best of our knowledge, compact multipass cell design for spin-exchange relaxation-free (SERF) atomic magnetometers, replacing conventional reflective cavities with a dual-parallel plate configuration. This adjustable planar reflector setup achieves precise control of reflection optical paths and dramatically enhances signal

Light emitters for on-chip SERF atomic magnetometers based on an inverse design method
Optics LettersOn-chip spin-exchange relaxation-free (SERF) atomic magnetometers (AMs) require linearly polarized light as detection light whose wavelength is 795 nm. In this study, we propose and demonstrate an inverse-designed linearly polarized light emitter suitable for 795 nm wavelength light. Due to the fact that the electric field of the TE

Performance optimization of a SERF atomic magnetometer based on flat-top light beam
Chinese Physics BWe explore the impact of pumping beams with different transverse intensity profiles on the performance of the spin-exchange relaxation-free (SERF) atomic magnetometers (AMs). We conduct experiments comparing the traditional Gaussian optically-pumped AM with that utilizing the flat-top optically-pumped (FTOP) method.
