This book describes various nonlinear phenomena in the radiation from plasmas, which are both fundamentally important because of the rich physics behind these phenomena, and also practically important as the most informative way to study laboratory and astrophysical plasmas is by analysing their radiation.

Nonlinearity is omnipresent in nature and in laboratory experiments. The nonlinear phenomena in the radiation from plasmas are fundamentally important because of the rich physics behind these phenomena. They are also practically important because the most informative way to study laboratory and astrophysical plasmas is by analysing their radiation. These nonlinear phenomena constitute the subject of this comprehensive book. First, the book covers various nonlinear phenomena occurring in plasmas containing quasimonochromic electric fields. Second, the book covers nonlinear phenomena manifesting in the Stark broadening of spectral lines by dynamic plasma electrons or ions. Many theoretical results presented in the book are counterintuitive, and are illustrated by numerous two-dimensional and three-dimensional plots. The book also describes various applications of the theoretical results for areas of diagnostics for laboratory and astrophysical plasmas.
