Photo-excited processes have applications on optoelectronics, physics, photochemistry, materials sciences, and a range of other fields. Gathering contributions from across the range, Peled (Holon Academic Institute of Technology, Israel) hopes these 12 chapters will serve as a "snapshot" of recent research and applications related to photo-excited processes. Chapters cover such topics as optical absorption and excitons in solids; dynamic waveguides and gratings in photo-refractive crystals; models for laser ablation; thin nitride films deposited by reactive pulsed laser ablations; liquid phase photodeposition processes from colloid structures; and carbon allotropes created by intense irradiation of frozen hydrocarbons.
