Processes leading to self-similarity of plasma dynamic properties in pulse gas discharge lasers (PGL) in a wide range of variation of initial conditions of the discharge are described. The first integrals of the equations and self-similar solutions of kinetic equations describing the evolution of plasma for a space self-maintained longitudinal high-current pulse-periodic discharge in a mixture of neon with metal vapors (copper, barium) are presented. The characteristics of discharge plasma in similar schemes of excitation are the same and can be described by the self-similar solutions. Possible mechanisms, restricting the plasma self-similarity in a pulse-periodic PGL discharge during the time of a current pulse are discussed.
