摘  要:In this paper,the influence of the delay time between the pre-pulse and the main pulse on the double-pass amplified 46.9 nm laser was studied for the first time,to the best of our knowledge,by using a high-precision polished SiC slice as a rear mirror.The temporal and spatial characteristics of the output laser were measured separately to investigate the effect of the delay time on the laser characteristics.The energy of the double-pass amplified laser was between 510μJ and 890μJ.In addition,a theoretical model of double-pass amplification was established to analyze the effect of the delay time on the double-pass amplified 46.9 nm laser.
