Atom, molecule or radical can be excited to a specific intermediate state by absorbing m laser photons, then the parent ion can be produced by absorption of another n laser photons. The ion yield can be increased drastically due to resonant absorption, comparing with the ion yield in non-resonant absorption. This multiphoton process is usully called Resonance Enhanced Multiphoton Ionization. REMPI technique plays an important role in detecting the high electronic excited states of atoms, molecules and radicals.
