Grujić, Zoran D. Weis, Antoine 2013-07-12 In recent years diode laser sources have become widespread and reliable tools in magneto-optical spectroscopy. In particular, laser-driven atomic magnetometers have found a wide range of practical applications. More recently, so-called magnetically silent variants of atomic magnetometers have been developed. While in conventional magnetometers the magnetic resonance transitions between atomic sublevels are phase-coherently driven by a weak oscillating magnetic field, silent magnetometers use schemes in which either the frequency or the amplitude of the light beam is modulated. Here we present a theoretical model that yields algebraic expressions for the parameters of the multiple resonances that occur when either amplitude-, frequency-, or polarization-modulated light of circular polarization is used to drive the magnetic resonance transition in a transverse magnetic field. The relative magnitudes of the resonances that are observed in the transmitted light intensity at harmonic m of the Larmor frequency ω_L (either by DC or phase sensitive detection at harmonics q of the modulation frequency ω_mod) of the transmitted light are expressed in terms of the Fourier coefficients of the modulation function. Our approach is based on an atomic multipole moment representation that is valid for spin-oriented atomic states with arbitrary angular momentum F in the low light power limit. We find excellent quantitative agreement with an experimental case study using (square-wave) amplitude-modulated light. application/pdf https://folia.unifr.ch/global/documents/303185 https://folia.unifr.ch/documents/303185/files/wei_amr.pdf eng info:eu-repo/semantics/altIdentifier/doi/10.1103/PhysRevA.88.012508 info:eu-repo/semantics/openAccess License undefined Physical Review A. - 2013, vol. 88, no. 1, p. 012508 info:eu-repo/classification/udc/53 Atomic magnetic resonance induced by amplitude-, frequency-, or polarization-modulated light http://purl.org/coar/resource_type/c_6501
