Nucleation and Cluster Formationsirable. An example is PLD, where clusters formed within the vapor plume may condense on the substrate and thereby deteriorate epitaxial film growth. However, by employing a moderate background pressure, the same technique can be used to fabricate thin nanocrystalline films with unique physical properties.

Non-uniform Mediae materials, in multilayer structures, and in combined structures. Such structures may only be generated during laser processing, as in laser-induced surface oxidation or deposition of thin films or microstructures.

Nanosecond-Laser Ablationis less suggestive with respect to the fundamental mechanisms involved in the process. PLA permits one to widely suppress the dissipation of the excitation energy beyond the volume that is ablated during the pulse.

Ultrashort-Pulse Laser Ablationiminished with picosecond pulses, and can even be ignored with femtosecond pulses, material removal is very localized and requires less energy. With ultrashort pulses, ablation mechanisms that are of minor relevance or not at all present in nanosecond-laser ablation become increasingly important.
