Abstract
The Vlasov susceptibility for two interacting electromagnetic waves is derived by using an extended version of the ‘‘κ–χ theorem.’’ The plasma is relativistic and magnetized. It is allowed for arbitrary k⊥ρ, ω/Ω, k⊥/k∥, and v/c. Nonuniformities in the background quasistatic magnetic field are also included. As an application, a general expression for the free‐electron laser susceptibility is derived.
