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 کاملMeasurement Sensitivity Improvement of All-Optical Atomic Spin Magnetometer by Suppressing Noises
Quantum manipulation technology and photoelectric detection technology have jointly facilitated the rapid development of ultra-sensitive atomic spin magnetometers. To improve the output signal and sensitivity of the spin-exchange-relaxation-free (SERF) atomic spin magnetometer, the noises influencing on the output signal and the sensitivity were analyzed, and the corresponding noise suppression...
متن کاملQuantum-enhanced Optical Magnetometer Using Squeezed Light in Atomic Vapor
We have built an optical magnetometer based on the nonlinear Faraday effect in hot Rb vapor and probe this device with both coherent light and polarization-squeezed light. We generate the squeezed light states using the polarization self-rotation effect in Rb vapor, optimized for the highest noise suppression, giving us a system which is allatomic. By probing with polarization-squeezed states o...
متن کاملMagnetic resonance imaging with an optical atomic magnetometer.
We report an approach for the detection of magnetic resonance imaging without superconducting magnets and cryogenics: optical atomic magnetometry. This technique possesses a high sensitivity independent of the strength of the static magnetic field, extending the applicability of magnetic resonance imaging to low magnetic fields and eliminating imaging artifacts associated with high fields. By c...
