plasma shielding

in laser induced breakdown spectroscopy
https://doi.org/10.1351/goldbook.08524
Prevention of laser pulse energy from reaching a sample surface as a result of the presence of a laser-induced plasma.
Note: The main process leading to plasma shielding is the absorption of the laser energy by electrons (inverse Bremsstrahlung) and multiphoton ionization (mainly relevant for shorter laser wavelengths).
