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).
