Laser ablation

Preparation technique which uses a laser to vaporize a graphite target to create a carbon plume, which is the precursor for growth of amorphous carbon, diamond like carbon, carbon nanotubes, or fullerenes.

NOTE. Either a continuous or pulsed laser can be used, the latter giving rise to the terms pulsed laser ablation (PLR) and pulsed laser deposition (PLD).

Laser ablation is the process of removing material from a solid (or occasionally liquid) surface by irradiating it with a laser beam. At low laser flux, the material is heated by the absorbed laser energy and evaporates or sublimates. At high laser flux, the material is typically converted to a plasma. Usually, laser ablation refers to removing material with a pulsed laser, but it is possible to ablate material with a continuous wave laser beam if the laser intensity is high enough.
