    American Institute of Physics. @S0021-9606~96!02519-X# I. INTRODUCTION Optical pumping has been researched extensively in the past few decades following the pioneering work of Kastler in the 1950’s.1 Recently there has been an increased amount of study involving the indirect pumping …


  • OSA | Interplay between optical pumping and Rydberg EIT in ...

    The asymmetry of the EIT spectra, which is caused by the quadratic Zeeman effect of the intermediate state, becomes paramount in magnetic fields ≥40 Gauss. We investigate the interplay between Rydberg EIT, which reduces photon scattering, and optical pumping, which relies on photon scattering.

  • Lasers for Optical Pumping & EIT

    Optical pumping is widely used to prepare atoms, ions or molecules in a selected quantum mechanical state. This can be either a specific electronic state (like in a gas or solid state laser itself) or a magnetic state. The latter is a prerequisite for laser magnetic field measurement and for monitoring the lung with NMR/MRT techniques involving ...


  • Optical pumping - Wikipedia

    Optical pumping is a process in which light is used to raise (or "pump") electrons from a lower energy level in an atom or molecule to a higher one. It is commonly used in laser construction, to pump the active laser medium so as to achieve population inversion.
