Abstract: The present disclosure provides a self-similar regenerative amplification method and an apparatus. The apparatus includes a broadband seed source, a spectrum shaping broader, a self-similar regenerative amplifier and a pulse compressor disposed in order of a light path. The spectrum shaping broader includes a time domain broader and a spectrum shaper. The time domain broader is configured to broaden the seed pulses, and fine-tune a width of the seed pulse. The spectrum shaper is configured to perform spectrum shaping on the broadened pulses to obtain saddle chirped pulses. The pulse regenerative amplification component includes a gain crystal and a nonlinear crystal. The self-similar regenerative amplifier receives the saddle chirped pulses, performs multiple stepwise amplifications and multiple nonlinear spectrum broadenings back and forth on the saddle chirped pulses, and output high-energy chirped pulses to the pulse compressor.
