Oscillator-strength enhancement of electric-dipole-forbidden transitions in evanescent light at total reflection
Year: 2005
Type: article
Abstract: The absorption line strengths of electric-dipole-forbidden (magnetic dipole and electric quadrupole) transitions have been calculated in the evanescent light field that accompanies the total reflection of light. Owing to the complex wave and polarization vectors of the evanescent light, the apparent oscillator strength is enhanced from that in the propagating light and the enhancement for the electric quadrupole transition depends on the polarization vector of the incident light. Separation of the contribution from each component of the wave and polarization vectors is proposed with a magnetic-sublevel-resolved measurement for the $(s\text{\ensuremath{-}}d)$ electric quadrupole transition.
