Magnetically-controlled velocity selection in a cold atom sample using stimulated Raman transitions

2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/145267We observe velocity-selective two-photon resonances in a cold atom cloud in the presence of a magnetic field. We use these resonances to demonstrate a simple magnetometer with sub-mG resolution. The technique is particularly useful for zeroing the magnetic field and does not require any additional laser frequencies than are already used for standard magneto-optical traps. We verify the effects using Faraday rotation spectroscopy.5 pages, 6 figuresQuantum PhysicsMagnetically-controlled velocity selection in a cold atom sample using stimulated Raman transitionstext
