Abstract. Integrated criteria of optical homogeneity of high-power laser active medium are discussed. Optimization of laser amplifier is shown to account for both power characteristics and effectiveness of laser radiation energy transmission to operation zone. Specifics of optimal scaling for laser amplifier operated under linear and saturated amplification conditions for regular and statistical phase inhomogeneity of the active medium are revealed.
