Abstract
Strong optical pumping of ions can result after a few microseconds of resonance excitation in a laser beam. However, both Fokker-Planck diffusion and acceleration due to macroscopic electric fields can remove an ion from resonance by changing the ion velocity on a similar timescale. Therefore, the time dependence of laser induced fluorescence can be influenced by particle acceleration and velocity-space diffusion. This effect which has already been used to measured Fokker-Planck diffusion, is extended to include the influence of an electric field and used to measure the electric field associated with an electrostatic shock in a multipolar gas discharge.
