The interaction of partially ionized plasmas with an electromagnetic field is investigated using quantum statistical methods. A general statistical expression for the current density of a plasma in an electromagnetic field is presented and considered in the linear response and the high field regime. Expressions for the collisional absorption (inverse bremsstrahlung) are derived and discussed. In addition, results of molecular dynamics simulations are shown. Further, partially ionized plasmas are considered. Plasma Bloch equations for the description of bound–free transitions are given and the absorption coefficient as well as rate coefficients for multiphoton ionization are presented.
