Summary:

This book examines the theory and applications of laser-induced plasmas. Topics discussed include the application of laser-induced plasma expansion models for thin film deposition; cluster-containing plasma fumes for high-order harmonic generation laser radiation; pulsed laser deposition of nanocrystalline V2O5 thin films; nanosecond and femtosecond laser ablation of TeO2 crystals; resonant harmonic generation of short pulse laser in plasma and the influence of the heterogeneous nature of laser ablation on near-surface plasma formation and propagation.
