Local plasma formed by the interaction between a laser beam and a solid sample and initiated by the production of primary electrons by multiphoton ionization and thermionic photoemission mechanisms.
Note: As well as electrons, laser-induced plasma contains ions, and neutral atoms as well as excited species of the ablated matter. Decay of these excited species generates the light emission analysed in
laser-induced breakdown spectroscopy.
