Abstract: Disclosed is a method and standard module for amplifying pulsed power. The key point of the technical solution is as follows: a method for amplifying pulsed power is formed by means of the joint action of a LASER mode of a crystal medium, a carrier multiplication amplification mode of a semiconductor medium, and a plasma breakdown amplification mode of a gas medium. Electric power which is amplified is converted into optical power first, the optical power is amplified again, and the amplified optical power is converted into electric power again by a photoelectric conversion and amplification device. A gas switch is triggered based on a photoconductive switch to generate a timing-synchronized high-power electric pulse. The high-power electric pulse may be directly outputted or distributed in multiple channels to obtain multiple timing-synchronized trigger signals. In combination with pulse charge of a capacitor, multiple timing-synchronized high-power electric pulses are outputted.
