A spectra shaping scheme for chirped pulse amplification (CPA), uses a CTSI spectral decomposition system (6, 2, 3, 4, 10), a CTSI spectral synthesizing system (4', 3', 2', 6'), and a spectral modulating ing system (10, 5), wherein the CTSI spectral decomposition system (6, 2, 3, 4, 10) and CTSI spectral synthesizing system (4', 3', 2', 6') are symmetrical to each other. The scheme includes the following steps: totally and truly expanding the laser chirped pulse to the spectral plane by the CTSI spectral decomposition system (6, 2, 3, 4, 10), performing the spectral modulation on the image plane by the spectral modulating system (10, 5), and reverting the modulated spectra into the chirped pulse without distortionby the CTSI spectral synthesizing system (4', 3', 2', 6'), thereby realizing the spectra shaping.
