An isotropic earth field scalar magnetometer using optically pumped helium 4
Optical pumping was originally suggested by Kastler [I] in 1950 and since the early 1960's numerous helium magnetometers based upon that technique have been developed. Since then the main evolution has consisted in the advent in 1986 of tunable lasers suitable for helium optical pumping. They led to a renewed interest in helium magnetometry essentially because the magnetometer resolution is exp...
متن کاملHigh Sample Rate Optically Pumped Helium Magnetometer
Optically pumped helium magnetometers are important instruments whichhave many applications in military, mass spectroscopy and space applications. In thispaper, the working principles of helium magnetometers have been explained. There isalso an introduction of a new method for finding the resonant frequency, which hasadvantages to the typical method such as more sample r...
متن کاملSensitive 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 کاملOptical pumping of helium with arc lamp excited LNA lasers
2014 We have developed a compact and relatively inexpensive laser source at 03BB =1.083 03BCm, suitable for optical pumping in helium. The laser is made of an LNA crystal transversely pumped by krypton arc lamps. A cw power of 800 mW has been achieved at 1.083 03BCm with a 3 GHz bandwidth. A 66 % nuclear polarization has been obtained in a 3He gas. Revue Phys. Appl. 24 (1989) 827-831 AOÛT 1989,
متن کاملAlignment of a vector magnetometer to an optical prism.
A method for alignment of a vector magnetometer to a rigidly attached prism is presented. This enables optical comparison of the magnetometer axes to physical surfaces in the apparatus, and thus an absolute determination of the magnetic field direction in space. This is in contrast with more common techniques, which focus on precise determination of the relative angles between magnetometer axes...
