Rashid A. Ganeev is an internationally recognized expert in the field of High Harmonic Generation (HHG) in laser ablation plasmas. In the present book, he specifically addresses the case of extended ablation plasmas as nonlinear media for HHG. The book describes the different experimental approaches, shows the advantages and limitations regarding HHG efficiency and discusses the particular processes that take place at longer interaction lengths, including propagation and quasi-phase matching effects. Several schemes have been proposed such as exploitation of a resonance between pump laser and driven matter, use of nano-molecules and metal clusters, use on modulated extended plasmas and so on. The structure of the book follows a logical presentation of first providing an overview of HHG in short length ablation plasma plumes and introducing in the following chapters the different experimental approaches tested to generate longer plumes. The results presented are a recollection of the author´s own contributions but there are also plenty of references to publications by other actors in the field. The book shows the perspectives of further development of HHG in extended plasma plumes. It also provides an updated recollection of the subject of plasma harmonics, which will be useful for students and scholars working in this highly multidisciplinary domain encountering material science, nonlinear optics and laser spectroscopy. The present book brings the new researcher at the very frontier of the physics of the interaction between laser and extended plasma; it will serve to the expert as an essential compass to follow a predetermined path.
