The goal of the book is to present the high-power high-frequency pulse periodic laser systems, which in the nearest time will find a lot of applications in the field of ecology, machinery, space engineering, nuclear technologies and many others. A laser-plasma generator of multiply charged ions produces a large number of heavy ions in the regime of short periodic pulses, which is needed for ion accelerators operating in the pulse periodic regime. The source of this type is also promising for effective use in the field of heavy-ion fusion, brittle materials figure cutting, oil films elimination from the water surface and so on. This book has considered, in details, a new approach to the problem of a laser jet engine creation, which is based on the resonance merging of shock waves generated by an optical pulsating discharge, produced by such a laser. To obtain an optical pulsating discharge, the authors suggested the usage of high-power pulse-periodic laser radiation, which can be generated by wide aperture carbon dioxide, chemical and mono-module disk type solid-state laser systems. Future developments of the disk laser technology as the most effective and scalable to the level of many hundreds of kW as well are under consideration in the book.
