The book introduces ‘the state of the art' of pulsed laser
ablation and its applications. It is based on recent theoretical
and experimental studies. The book reaches from the basics to
advanced topics of pulsed laser ablation. Theoretical and
experimental fundamental phenomena involved in pulsed laser
ablation are discussed with respect to material properties, laser
wavelength, fluence and intensity regime of the light absorbed
linearly or non-linearly in the target material. The energy
absorbed by the electrons leads to atom/molecule excitation,
ionization and/or direct chemical bond breaking and is also
transferred to the lattice leading to material heating and phase
transitions. Experimental non-invasive optical methods for
analyzing these phenomena in real time are described. Theoretical
models for pulsed laser ablation and phase transitions induced by
laser beams and laser-vapour/plasma interaction during the plume
expansion above the target are also presented. Calculations of the
ablation speed and dimensions of the ablated micro- and
nano-structures are performed. The validity and required refinement
of different models in different experimental conditions is
provided. The pulsed laser deposition process which bases on
collecting the ablated particles on a surface is analyzed in terms
of efficiency and quality of the deposited films as a function of
ambient conditions, target material, laser parameters and substrate
characteristics. The interaction between the incident laser and the
ablation plasma is analyzed with respect to its influence on the
structures of the deposited films and its capacity to generate high
harmonics and single attosecond pulses which are highly desirable
in pump-probe experiments.
