In the field of optics, coupled light sources (e.g., lasers) can influence each other, producing ... A team of physicists and engineers at the University of Colorado Boulder has discovered a new ...

and the spin of the outermost single electron can be easily manipulated by optical pumping and other methods. As a result, atomic magnetometers all choose alkali metal atoms as working substances.

These sources make use of optical nonlinear effects in specially designed optical fibres to create light with a wide spectrum that can span the visible and near-infrared, typically from around 400 ...
