Laser-Plasma Interactions 4 is the fourth book in a series devoted to the study of laser-plasma interactions. Subjects covered include laser light propagation, instabilities, compression and hydrodynamics, spectroscopy, diagnostics, computer code, dense plasmas, high-power lasers, X-UV sources and lasers, beat waves, and transport processes.Introduction to the physics and applications of laser-produced plasmas M.H.
